Technical Data and Specifications Frequency Enclosures Series-Multiple Windings Sound Levels Eaton standard low-voltage dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Eaton's ventilated transformers, Types DS-3 and DT-3, use a NEMA 2 rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields. Transformers manufactured in enclosures 939, 940, 942, 943, 944 and 945 are UL Listed to be installed indoors (without weathershields) with just 2 inches clearance on the sides and rear of the transformer. Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an "x" or "/" between the voltage ratings, such as voltages of "120/240" or "240 x 480." If the series-multiple winding is designated by an "x," the winding can be connected only for a series or parallel. Winding Terminations With the "/" designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 120 x 240 winding can be connected for either 120 (parallel) or 240 (series), but a 120/240 winding can be connected for 120 (parallel), or 240 (series), or 240 with a 120 mid-point. All Eaton 600 volt class DOE 2016 low-voltage general-purpose dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher (as much as 15 dB greater) due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. Overload Capability Short-term overload is designed into transformers as required by ANSI. Lowvoltage dry-type distribution transformers will deliver 200% nameplate load for one-half hour, 150% load for one hour and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Rise Industry standards classify insulation systems and rise as shown below: Insulation System Classification 2 2 Ambient + Winding Rise + Hot Spot = Temp.

Primary and secondary windings are terminated in the wiring compartment. Ventilated transformers have leads brought out to terminals that are pre-drilled to accept Cu/Al lugs. Aluminum-wound transformers have aluminum terminals; copper-wound models have copper terminals; aluminum and copper transformers include double neutral. Lugs are not supplied with these transformers. Eaton recommends external cables be rated 75C for ventilated designs. For additional information, please refer to Section 2.7 Page V2-T2-167.

The larger the K-factor, the more harmonics are present. Linear loads, for example, have a K-factor of 1. Transformers may carry a K-factor rating to define the transformer's ability to withstand the additional heating generated by harmonic currents. Eaton K-Factor transformers are specifically designed to withstand the harmful overheating effects caused by harmonics generated by nonlinear (non-sinusoidal) loads. These loads include computers, laser printers, copiers and other office equipment, as well as video monitors and other electronic equipment. Eaton K-Factor transformers are not simply over-sized transformers. The core and coils of our K-Factor transformers are specially designed to have reduced induction levels, which results in a reduction in stray losses. Oversized (200% rated) neutrals and electrostatic shielding are typical features found in our K-Factor transformers. Eaton K-Factor transformers are manufactured with the same high-quality construction features as our other ventilated transformer products, including NEMA 2 enclosures as standard. 2 Calculating the K-Factor All nonlinear waveforms can be broken down mathematically into a fundamental frequency and its harmonics. IEEE C57.110 establishes a direct relationship between these harmonics and transformer heating. Underwriters Laboratories has established a similar relationship, the K-factor, which is derived by summing the square of the percentage current at a given harmonic level multiplied by the square of the harmonic order. K = (Ih)2(h)2 Ih = Percent Current at Harmonic h h = Harmonic Order, i.e., 3rd, 5th, 7th For example, a load that is 90% of the fundamental, 30% of the third harmonic, and 20% of the fifth harmonic would yield (.9)2(1)2 + (.3)2(3)2 + (.2)2(5)2 or a K-factor of 2.62. This load would require an Eaton KT-4 transformer with a K-factor rating of 4. Transformers that carry a K-factor rating define the transformer's ability to withstand a given harmonic load while operating within the transformer's insulation class. An analysis of harmonic loads and a calculation of the K-factor must be made to properly apply transformers in any building or facility. Note that the calculated K-factor is not constant because nonlinear loads change throughout the day as equipment and lighting is turned off and on. These harmonic loads also change over the life of the building or facility as equipment is added or removed. 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 Volume 2--Commercial Distribution CA08100003E--April 2019 www.eaton.com V2-T2-29 2.2 2 2 2 2 2 2 2 2 2 2 Transformers DOE 2016 Energy-Efficient K-Factor Rated Transformers Harmonic Currents Harmonic currents are found in nonlinear loads. These currents are generated by various types of equipment including switching mode power supplies that abruptly switch current on and off during each line cycle. Switching mode power supplies or diode-capacitor power supplies convert AC line voltage to low voltage DC. This process is accomplished by charging capacitors during each line cycle with narrow pluses of current that are timecoincident with line voltage peaks. Examples of this equipment include electronic ballasts for fluorescent lighting, personal computers, printers, fax machines, electronic and medical test equipment, uninterruptible power supplies, and solid-state motor drives. Note: Nonlinear is synonymous with the term non-sinusoidal.

Three-phase DOE 2016 efficient transformers are provided with a bonding ground bar attached to the bottom panel for compliance with NEC 450.10(A) Electrostatic shield Note: Electrostatic shields do not reduce harmonic levels. However, because of the nature of switching mode loads, these shields do reduce transient noise in the system, which may affect sensitive computer loads. 2 2 2 2 2 Aluminum windings (copper optional) Class 220C insulation Reduced core flux density Note: Reduced core flux prevents the core from saturation and overheating due to voltage distortions caused by harmonic currents. 2 2 2 2 2 2 2 Indoor enclosures (weathershields optional, for outdoor applications) Coils designed to minimize stray losses K4, K13 standard K9, K20, K30 optional Low sound level (-3 dB, -5 dB) available as options 2 2 2 2 2 V2-T2-30 Volume 2--Commercial Distribution CA08100003E--April 2019 www.eaton.com Standards and Certifications UL listed Industry Standards All Eaton low-voltage dry-type distribution transformers are built and tested in accordance with applicable NEMA, ANSI and IEEE Standards.

Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Lowvoltage dry-type distribution transformers will deliver 200% nameplate load for one-half hour, 150% load for one hour, and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Electrostatic Shielding There are no industry standards for electrostatic shield performance. Eatonmanufactured transformers have been tested by an independent laboratory to meet the following attenuation levels: When tested per MIL-Std220A, Method of Insertion Loss Measurement, with matched impedance no load technique: Common mode noise attenuation: - Minus 80 dBA minimum at 0.1 kHz to 1.5 kHz; minus 55 dBA minimum at 1.51 kHz to 100 kHz Normal mode (Transverse mode) noise attenuation: - Minus 35 dBA minimum at 1.5 kHz to 10 kHz Primary to Secondary Capacitance of 24.74- 18.06 picofarads on the range 100-20 kHz Insulation System and Temperature Rise Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding Rise + Hot Spot = Temp. Class 40C 55C 10C 105C 40C 80C 30C 150C 25C 135C 20C 180C 40C 115C 30C 185C 40C 150C 30C 220C The design life of transformers having different insulation systems is the same--the lower-temperature systems are designed for the same life as the higher-temperature systems. 2 Sound Levels All Eaton 600 volt class general-purpose low-voltage dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. 2 Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. 2 For additional information, please refer to Section 2.7 Page V2-T2-171. 2 2 2 2 2 2 2 2 2 Average Sound Levels 2 NEMA ST-20 Average Sound Level, dB Equivalent Winding Self-Cooled Ventilated (up to 1.2 kV) kVA Range K-Factor 1, 4, 9 K-Factor 13, 20 Encapsulated (up to 1.2 kV) 2 3.00 and below 40 40 45 Enclosures 3.01 to 9.00 40 40 45 2 Eaton ventilated transformers, Type KT, use a NEMA 2 rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields.

For other ratings or catalog numbers not shown, or for special enclosure types (including stainless steel), refer to Eaton. The electrical transformer has been a staple of electrical power systems for the past 100+ years. While the types of electrical loads that are being added to our systems today have radically changed, the transformer has stayed relatively the same in design during this time frame. Eaton's harmonic mitigating transformer (HMT) represents the evolution of the transformer into something that will best provide clean, energyefficient electricity to power the loads of today and tomorrow. The recent shift of our electrical loads from predominately AC consumers (resistive heating elements, incandescent lighting, three-phase motor load) to DC consumers (such as computers, fax machines, printers, down to the "wall-wart" that recharges the cell phone) requires that our electrical infrastructure changes as well. These new loads now introduce other currents and frequencies into our electrical power systems--commonly known as "harmonics." Harmonic currents can cause additional heating, which may cause transformers, generators and conductors to become overloaded. Excessive heat is one of the major reasons that standard transformers and conductors fail prematurely. These harmonic currents have various other effects (such as "loss of ride-through capability," reduced lifespan and mysterious misoperation of equipment) on the components and loads of an electrical distribution system. Eaton's HMTs, when used properly within an electrical system, will help keep the loads operating the way the manufacturer designed them and keep the facility's electrical system free from voltage distortion. Three-Phase, Type DT-3 HMT, 60 Hz Harmonic mitigating (cancellation) transformers are a cost-effective means of treating harmful harmonics in an electrical distribution system Reducing harmonic content in electrical systems can result in a more reliable electrical system, lower maintenance costs, less downtime, fewer equipment malfunctions, and lower cooling system capacity Available in a variety of phase-shift configurations that allow flexibility to target specific families of harmonics Harmonic treatment via electromagnetic flux cancellation May be installed as a stand-alone transformer, or included in IFSTM Available in three-phase ratings, 15-500 kVA, up to 600 volts primary 2 2 2 V2-T2-64 Volume 2--Commercial Distribution CA08100003E--April 2019 www.eaton.com Page V2-T2-65 V2-T2-65 V2-T2-66 V2-T2-67 V2-T2-75 V2-T2-75 Transformers DOE 2016 Energy-Efficient Harmonic Mitigating Transformers Features and Benefits 480 volt to 208/120 volt standard.

Please refer to Section 2.7 Page V2-T2-167. 2 2 2 2 Technical Data and Specifications Frequency Eaton standard low-voltage dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capacity Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 200% nameplate load for one-half hour; 150% load for one hour and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading.

The use of power factor corrected computer power supplies is a great first start to reducing harmonic currents in your facility. These are becoming prevalent in server applications, but have not "crossed-over" into the laptop computer/business computer. Remember also that, once the computer power supply harmonics are addressed, you will still need to address the harmonic currents coming from the variety of other equipment in your facility. In understanding the product placement of the HMT, it becomes useful to have some "rule of thumb" understanding to compare products. Looking at one of the aspects of an HMT-- price--you can see that, if a standard delta-wye transformer had a cost of one unit, a K-13 transformer would cost about double and an HMT would cost 1.5 to 4 times the unit cost. What's impressive to compare is the next column of information-- "Energy Savings." If the amount of energy used to power today's loads is compared against a standard delta-wye transformer (that was never designed to feed today's types of loads), you can easily see that the HMT is designed to meet the issue head-on! Referring to the table's information, you can see that it would take 30% more energy to power the same computer loads with a K-13 transformer, whereas an HMT would take 25% less energy to feed those same computer loads. 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 Don't K-rated transformers fix harmonics? The K-rated transformer was created to address the additional heat being produced by standard deltawye transformers when feeding nonlinear loads. The goal of the K-rated transformer is to dissipate the heat produced over a larger area, thus providing the illusion of correction. The K-rated transformer does nothing to reduce the root issue of harmonic currents or correct power quality issues. Because of their larger size, they also consume additional energy to "do the same work" and are counter-productive to an energy-efficient electrical distribution design. Don't you need two HMTs for any correction to occur? The design of HMTs allows them to address different families of harmonic currents in different ways. A single HMT will treat the triplen (3rd, 9th, 15th and so on) harmonic currents in its secondary winding. The 5th, 7th, 17th and 19th harmonic family is treated on a system basis through a technique known as "phase shifting." This phase shift does occur between the Type NON and Type THR, and the Type POS and Type NEG harmonic mitigating transformers--and this can also occur between a Type NON and a standard delta-wye transformer (that is probably already existing within your facility). See our Sample HMT Applications area for additional information. The cost of HMTs is too high! While the initial cost of HMTs is typically 1.5 to 4 times the cost of a standard transformer (due to the additional design, materials and labor involved in creating the magnetics necessary to reduce harmonic impact)--to not use an HMT in a harmonic environment will actually cost you 250% more energy loss in the transformer. Due to the relatively long life of a transformer (20-30 years), these additional energy costs easily overshadow the initial one-time first cost increment. If I use one HMT, don't I need to change all my transformers? Most facilities have only a percentage (typically 20-25%) of their electrical system that really requires the use of an HMT. This means in a typical building that only a few areas are either critical (meaning high requirements for "clean" power) or have high concentrations of electronic, nonlinear loads--requiring the use of the HMT in those specific areas. The harmonic mitigating transformer is a weapon in your arsenal in providing a complete, properly designed electrical system for today and tomorrow. Transformer Technology Comparison 1 Transformer Type Cost Energy Savings Power Quality Standard delta-wye if 1X if 1X Not designed for harmonics K-13 1.5-2X -0.3X Bulked up--doesn't help HMT 2.5X 2.5X Corrects root issue Note 1 Comparing cost, energy savings and power quality performance between the "commonly used" transformer types. 2 2 2 V2-T2-76 (This is due to the fact that the HMT has a different design than a standard deltawye transformer and addresses the root issue of harmonic currents.) A good analogy is to look at the incandescent light bulb versus a compact fluorescent lamp--you might pay a bit more up front, but because of the large energy savings (because of the harmonic loading), you soon realize that the upfront cost pales in comparison to the potential of energy saved. Eaton would be happy to provide you with an estimation calculator to help you determine the amount of payback and return on investment (ROI) based on the incremental cost of the HMT. It's very typical to return the price differential between the HMT and a standard transformer with a few years--thus using the additional 20 to 30 years of energy savings to add to your bottom line.

Triplen harmonic currents are treated in the secondary windings of the transformer due to the transformer's low zero sequence impedance. Type NON transformers do not need to be used in combination with other transformers to treat triplen harmonic currents. A single Type NON transformer may be installed, or multiple units can be applied. 2 Type NON Long Run Long Run Type NON transformers are an ideal solution for treating triplen harmonics generated by personal computers, printers, fax machines and other office equipment, as well as by single-phase electronic ballasts, and singlephase electronic testing or monitoring devices. Electrical Bus When a delta-wye transformer exists in an electrical distribution system, the addition of a Type NON transformer offers an economical solution for treating harmonic currents. The 30 phase-shift created between a Type NON harmonic mitigating transformer and a delta-wye transformer (standard transformer or K-Factor transformer) provides treatment of 5th, 7th, 17th and 19th harmonic currents. These harmonic currents are canceled in the common electrical bus that feeds the transformers. 2 2 -Y Transformer 2 Additionally, triplen (3rd, 9th, 15th and so on) harmonic currents generated by the loads connected to the Type NON transformer will be treated in the secondary windings of the Type NON transformer due to its low zero sequence impedance. When using two or more transformers to treat harmonics, it is better that the load be split equally between the transformers to receive the maximum benefit. Note: Triplen currents will still circulate in the delta-wye transformer for additional waste.

The 30 phase shift created between Type NON and type THR harmonic mitigating transformers provides treatment of 5th, 7th, 17th and 19th harmonic currents. These harmonic currents are canceled in the common electrical bus that feeds the transformers. 2 Additionally,triplen (3rd, 9th, 15th and so on) harmonic currents generated by the loads will be treated in the secondary windings of HMTs. This will ensure that these currents will not circulate in the primary of the transformer creating additional heat, voltage distortion and wasted energy loss. When using two or more transformers to treat harmonics, it is better that the load be split equally between the transformers to receive the maximum benefit. Electrical Bus The combination of a Type POS (+15 phase-shift) transformer and a Type NEG (-15 phase-shift) transformer effectively treats 5th, 7th, 17th and 19th harmonic currents. These harmonic currents are canceled in the common electrical bus that feeds the transformers. 2 2 2 2 2 2 2 2 2 2 2 2 V2-T2-78 Volume 2--Commercial Distribution CA08100003E--April 2019 www.eaton.com Type POS Additionally, triplen (3rd, 9th, 15th and so on) harmonic currents generated by the loads connected to these transformers will be treated in their secondary windings due to their low zero sequence impedance.

Transformers required for other frequencies are available and must be specifically designed. Eaton encapsulated transformers, Types EP and EPT, use a NEMA 3R rated enclosure as standard. NEMA 4X enclosures (grade 304 or 316 stainless steel) are available as an option. Overload Capability Winding Terminations Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 200% nameplate load for one-half hour, 150% load for one hour and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or stabs brought out for connections. Eaton recommends that external cables be rated 90C (sized at 75C ampacity) for encapsulated designs. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Rise Industry standards classify insulation systems and rise as shown below: Insulation System Classification Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an "x" or "/" between the voltage ratings, such as voltages of "120/240" or "240 x 480." If the series-multiple winding is designated by an "x," the winding can be connected only for a series or parallel. With the "/" designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 120 x 240 winding can be connected for either 120 (parallel) or 240 (series), but a 120/240 winding can be connected for 120 (parallel), 240 (series) or 240 with a 120 mid-point. Sound Levels 2 All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. 2 2 2 2 2 2 Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. 2 2 2 For additional information, please refer to Section 2.7 Page V2-T2-171. 2 2 Average Sound Levels NEMA ST-20 Average Sound Level, dB Equivalent Winding Self-Cooled Ventilated (up to 1.2 kV) kVA Range K-Factor 1, 4, 9 K-Factor 13, 20 Encapsulated (up to 1.2 kV) 3.00 and below 45 40 40 3.01 to 9.00 40 40 45 9.01 to 15.00 45 45 50 15.01 to 30.00 45 45 50 30.01 to 50.00 45 48 50 50.01 to 75.00 50 53 55 75.01 to 112.50 50 53 55 112.51 to 150.00 50 53 55 150.01 to 225.00 55 58 57 225.01 to 300.00 55 58 57 300.01 to 500.00 60 63 59 500.01 to 700.00 62 65 61 2 2 2 2 2 Ambient + Winding Rise + Hot Spot = Temp.

Thermoguards are not available on encapsulated designs Totally enclosed non-ventilated Electrostatic shields Please refer to Section 2.7 Page V2-T2-167. Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 200% nameplate load for one-half hour, 150% load for one hour and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Rise Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding Rise + Hot Spot = Temp. Class 40C 55C 10C 105C 40C 80C 30C 150C 25C 135C 20C 180C 40C 115C 30C 185C 40C 150C 30C 220C The design life of transformers having different insulation systems is the same--the lower-temperature systems are designed for the same life as the higher-temperature systems. Enclosures Eaton ventilated transformers, Type MD, use a NEMA 2 rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Ventilated transformers have leads brought out to aluminum pads that are predrilled to accept Cu/Al lugs. Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 75C for ventilated designs. For additional information, please refer to Section 2.7 Page V2-T2-171.

Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 200% nameplate load for one-half hour, 150% load for one hour and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Rise Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding Rise + Hot Spot = Temp. Class 40C 55C 10C 105C 40C 80C 30C 150C 25C 135C 20C 180C 40C 115C 30C 185C 40C 150C 30C 220C The design life of transformers having different insulation systems is the same--the lower-temperature systems are designed for the same life as the higher-temperature systems. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions.

Suitable for indoor or outdoor applications Totally enclosed, nonventilated enclosures rated NEMA 3R 220C insulation system 150C rise standard; 115C or 80C rise optional Totally enclosed nonventilated transformers are specifically excluded from the scope of U.S. DOE energy efficiency requirements Application Description Totally enclosed nonventilated dry-type transformers are for special applications, where because of adverse atmospheric conditions it is desirable to use a dry-type non-ventilated transformer vs. the ventilated standard unit, which has openings in its enclosure to allow air to flow directly over the core and coil. In applications where the atmosphere contains conductive, corrosive, or combustible materials, which might damage a transformer, or lint and dust flyings that might block the ventilation passages, the non-ventilated transformer is highly suited. It has no openings in the enclosure. Heat is dissipated by radiating from the surface area of the enclosure. Consequently, the enclosures are larger than those of the standard ventilated type. Non-ventilated transformers are suited for application in the textile, chemical, automotive, petrochemical, foundry, cement, food, paper and other industries.

Totally enclosed nonventilated transformers have leads brought out to aluminum pads that are pre-drilled to accept Cu/Al lugs. Lugs are not supplied with these transformers. Eaton recommends external cables be rated 75C for ventilated designs. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an "x" or "/" between the voltage ratings, such as voltages of "120/240" or "240 x 480." If the series-multiple winding is designated by an "x," the winding can be connected only for a series or parallel. With the "/" designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 120 x 240 winding can be connected for either 120 (parallel) or 240 (series), but a 120/240 winding can be connected for 120 (parallel), or 240 (series), or 240 with a 120 mid-point.

Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 200% nameplate load for one-half hour, 150% load for one hour, and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. 2 2 Insulation System and Temperature Rise Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding Rise + Hot Spot = Temp. Class 40C 55C 10C 105C 40C 80C 30C 150C 25C 135C 20C 180C 40C 115C 30C 185C 40C 150C 30C 220C The design life of transformers having different insulation systems is the same--the lower-temperature systems are designed for the same life as the higher-temperature systems. Enclosures Eaton encapsulated transformers, Types EPZ and EPTZ, use a NEMA 3R rated enclosure. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. Winding Terminations Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 90C (sized at 75C ampacity) for encapsulated designs and 75C for ventilated designs. Unused tap leads must be properly insulated prior to energization. EPZ and EPTZ transformers are UL and cUL listed. 2 2 2 2 2 2 2 2 2 2 2 V2-T2-114 Volume 2--Commercial Distribution CA08100003E--April 2019 www.eaton.com Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple).

Eaton encapsulated transformers Types EPM and EPTM use a NEMA 3R rated enclosure. Type DT-3M transformers manufactured in enclosures 939, 940, 942, 943, 944 and 945 are UL Listed to be installed with just 2 inches clearance on the sides and rear of the transformer. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or stabs brought out for connections. Ventilated transformers have leads brought out to aluminum pads that are predrilled to accept Cu/Al lugs. Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 90C (sized at 75C ampacity) for encapsulated designs and 75C for ventilated designs. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an "x" or "/" between the voltage ratings, such as voltages of "120/240" or "240 x 480." If the seriesmultiple winding is designated by an "x," the winding can be connected only for a series or parallel. With the "/" designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 120 x 240 winding can be connected for either 120 (parallel) or 240 (series), but a 120/240 winding can be connected for 120 (parallel), 240 (series) or 240 with a 120 mid-point. Sound Levels All Eaton 600 volt class general-purpose low-voltage dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern.

For other ratings or catalog numbers not shown, or for special enclosure types (including stainless steel), refer to Eaton. Types EP, EPT Encapsulated design Suitable for indoor or outdoor applications Totally enclosed, nonventilated enclosures Enclosures are NEMA 3R rated Mountable in any position indoors and upright-only outdoors 180C insulation system 115C rise standard; 80C rise optional Available in single-phase ratings through 7.5 kVA Encapsulated transformers, such as buck-boost and lowvoltage lighting transformers, are specifically excluded from the scope of U.S. DOE energy efficiency requirements Application Description A buck-boost transformer is used to provide an economical method of correcting a lower or higher voltage rating more suitable for efficient operation of electrical equipment. Type EP buck-boost transformers are small kVA, single-phase transformers with dual primary and dual secondary windings, and are usually connected as autotransformers by using one unit for single-phase applications and either two or three units banked for threephase operation. They are primarily used for motor operation and should not be used for motor control circuits, to correct fluctuating line voltage or to obtain a neutral on a delta system. Buck-boost transformers are ideally suited for use with low-voltage lighting systems, such as outdoor lighting.

All 600 volt class transformers are UL listed unless otherwise noted. Seismically Qualified Eaton-manufactured dry-type distribution transformers are seismically qualified, and exceed requirements of the International Building Code (IBC) and California Code Title 24. Catalog Number Selection Please refer to Section 2.7 Page V2-T2-162. Transformers Distribution Transformers Product Selection For quick selection data, refer to the tables on this and the following pages. Selection Requirements You should have the following information before selecting a buck-boost transformer: Line Voltage The voltage that you want to buck (decrease) or boost (increase). This can be found by measuring the supply line voltage with a voltmeter. Load Voltage The voltage at which your equipment is designed to operate. This is listed on the nameplate of the load equipment. Load Amperes or Load kVA You do not need to know both--one or the other is sufficient for selection purposes. This information usually can be found on the nameplate of the equipment that you want to operate. Frequency The supply line frequency must be the same as the frequency of the equipment to be operated--Eaton's buck-boost transformers operate at 60 Hz only. Phase The supply line should be the same as the equipment to be operated--either singleor three-phase. Transformer Interconnection For three-phase applications, interconnections of transformers should be made in a junction box. Two or three transformers may be used depending on an open delta (2) or wye (3) connection. 2.5 120 x 240 Volts to 12/24 Volts 5-Step Selector The tables that follow will simplify the selection of the buck-boost transformers. There are no calculations needed; simply follow these five steps: 1. Refer to the table having the same output voltage as the equipment you want to operate. For example, if you are installing a 240 volt 6 kVA single-phase load use selection table on the page. 2. Select the available line voltage across the top of the chart that is closest to the actual supply voltage. Therefore, for example, if the available line voltage is 213 volts, use the 212 volt column. 3. Read down the column until you reach an output kVA or amps rating equal to or greater than the load requirements. Since 6 kVA, in the example, is not listed, use the next higher rating, or 7.5 kVA. 4. Read across to the far left columns for the catalog number and quantity of transformers for your application. In this case, you will need one (1) catalog number S10N06P01P. 5. Connect the buck-boost transformer(s) you have selected in accordance with the connection diagram specified at the bottom of the available line voltage column. In this example, Diagram "F" would be used. Note: For single-phase connections and three-phase open delta connections, inputs and outputs may be reversed. kVA capacity remains constant.

Dry-type distribution transformers will deliver 200% nameplate load for one-half hour, 150% load for one hour, and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or stabs brought out for connections. Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 90C (sized at 75C ampacity) for encapsulated designs. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Rise Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding Rise + Hot Spot = Temp. Class 40C 55C 10C 105C 40C 80C 30C 150C 25C 135C 20C 180C 40C 115C 30C 185C 40C 150C 30C 220C The design life of transformers having different insulation systems is the same--the lower-temperature systems are designed for the same life as the higher-temperature systems. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an "x" or "/" between the voltage ratings, such as voltages of "120/240" or "240 x 480." If the series-multiple winding is designated by an "x," the winding can be connected only for a series or parallel. With the "/" designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 120 x 240 winding can be connected for either 120 (parallel) or 240 (series), but a 120/240 winding can be connected for 120 (parallel), 240 (series) or 240 with a 120 mid-point. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. Note: When installation is to be made on a grounded system, consideration must be given to the resulting voltage. Thus, on a 208 grounded wye/120 system, the voltage can be boosted to 240 volts but the voltage to ground will be 139 volts. If 240/120 volts with a mid-point ground is needed, a standard two-winding transformer must be used. 2 The following formulas can be used to calculate specific requirements. 2 For single-phase: 2 2 2 2 2 2 2 For three-phase: 2 For additional information, please refer to Section 2.7 Page V2-T2-171. 2 2 Average Sound Levels 2 NEMA ST-20 Average Sound Level, dB Equivalent Winding Self-Cooled Ventilated (up to 1.2 kV) K-Factor 1, 4, 9 K-Factor 13, 20 kVA Range Encapsulated (up to 1.2 kV) 2 3.00 and below 45 2 40 40 3.01 to 9.00 40 40 45 9.01 to 15.00 45 45 50 15.01 to 30.00 45 45 50 30.01 to 50.00 45 48 50 50.01 to 75.00 50 53 55 75.01 to 112.50 50 53 55 112.51 to 150.00 50 53 55 150.01 to 225.00 55 58 57 225.01 to 300.00 55 58 57 300.01 to 500.00 60 63 59 2 2 2 2 2 2 500.01 to 700.00 62 65 61 700.01 to 1000.00 64 67 63 Greater than 1000 Consult factory Consult factory Consult factory 2 2 2 2 2 2 Volume 2--Commercial Distribution CA08100003E--April 2019 www.eaton.com V2-T2-147 2.5 Transformers Distribution Transformers 2 Wiring Diagrams 2 Buck-Boost Transformers Wiring Diagrams Diagram A Diagram B 2 2 2 2 X4 X1 X2 H4 H3 H4 H2 H1 H2 X1 X2 X3 H4 H3 H2 H1 X1 X2 H4 H3 X4 H2 X4 X3 X2 X1 H1 H1 H2 X3 X4 X1 X2 X2 H3 H2 H1 X4 X3 X4 X3 X2 X1 H4 H3 H2 H1 H1 H2 H3 H4 Low Voltage X3 X2 X1 X4 X3 X2 X1 X4 X3 X4 X3 X4 X3 X4 X3 X2 X4 X2 H3 H4 H3 H4 H3 H4 H3 X1 H4 X2 H3 X1 H4 X2 H3 X1 H4 X2 H3 H2 H1 H2 H1 H2 H1 H2 H1 H2 H1 H2 H1 H2 H1 H2 H1 Neutral X2 X4 X2 X1 X3 H4 H3 H4 H3 H4 H3 H2 H1 H2 H1 H2 H1 High Voltage X3 X4 X3 X4 X3 X4 X1 X2 X1 X2 X1 X2 H3 H4 Neutral High Voltage Diagram S 1 H1 H2 H3 H4 H1 H2 X2 H1 H3 H4 X2 X1 H1 H2 High Voltage X4 X3 H3 H4 X1 X3 X1 X3 X4 X2 X4 X2 H3 H1 H3 H1 H3 H1 H4 H2 H4 H2 X4 H4 H2 Low Voltage Neutral Diagram U High Voltage High Voltage X4 X3 X3 X2 Neutral Diagram T X1 X1 H3 H1 H4 H2 Low Voltage Low Voltage Neutral Diagram R 1 X4 X3 X4 High Voltage Neutral Low Voltage High Voltage X1 2 H1 H2 H3 H4 X1 H4 X4 H2 H4 H3 H2 H1 X2 H3 X3 H3 X4 X3 X2 X1 X1 H4 X1 H4 X1 X2 X3 X4 Diagram O 1 Low Voltage X3 H1 H2 H3 H4 High Voltage Diagram Q 1 X2 X1 Low Voltage X4 Diagram P 1 2 X3 X2 High Voltage Low Voltage X2 X4 X2 Low Voltage X1 X2 X3 X4 X1 X1 H4 X4 X1 Diagram L Diagram N 1 X3 H1 X3 H4 H3 H2 H1 H1 High Voltage X4 H2 High Voltage Low Voltage Diagram M 1 X3 H3 X4 Low Voltage High Voltage X2 2 H4 Low Voltage X4 X1 H1 H2 H1 X3 2 H2 X2 X3 Diagram I Low Voltage 2 X1 High Voltage X1 H2 2 2 H3 High Voltage 2 2 X2 Diagram K 2 2 X4 High Voltage 2 High Voltage Low Voltage X3 H1 High Voltage X1 H4 Diagram J 2 H3 H2 Diagram H 2 2 H4 H1 X3 Low Voltage 2 H3 Diagram F X4 Diagram G 2 X2 High Voltage High Voltage 2 X4 X1 X4 Diagram E Low Voltage 2 X3 X2 X3 Low Voltage Diagram D 2 2 X1 Low Voltage 2 Low Voltage High Voltage X3 2 2 Diagram C High Voltage X3 X4 X4 X3 X1 X2 X2 X1 X3 X4 X1 X2 H1 H2 Neutral H4 H1 H1 H4 Low Voltage H1 H4 Low Voltage Note 1 WARNING!

The shields protect the transformer top ventilation openings against rain but allow for proper ventilation. Field installation hardware is not required. Refer to specific transformer listing for selection of weathershield kit. Proper installation provides a NEMA 3R rating. Note: For 316 stainless steel, add the suffix `S' to the catalog number. A terminal extension kit is used to allow front access to the rear terminals on most 500 and 750 kVA transformers (transformers on frames 919 and 920) when insufficient space is available at the rear of the transformer. Eaton recommends a minimum 6-inch clearance from the wall to maintain proper ventilation.

Primary and secondary terminal lugs are not included. Lug kits are available separately. Overload Capability Short-term overload capacity is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 200% nameplate load for one-half hour, 150% load for one hour and 125% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Seismically Qualified Eaton manufactured dry-type distribution transformers are seismically qualified, and exceed requirements of the Uniform Building Code (UBC) and California Code Title 24. Taps Primary taps are available in most ratings to allow compensation for source voltage variations. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with a "x" or "/" between the voltage ratings, such as voltages of "120/240" or "240 x 480." If the series-multiple winding is designated by an "x," the winding can be connected only for a series or parallel. With the "/" designation, a midpoint also becomes available in addition to the series or parallel connection. As an example, a 120 x 240 winding can be connected for either 120 (parallel) or 240 (series), but a 120/240 winding can be connected for 120 (parallel), 240 (series) or 240 with a 120 midpoint. Enclosures Eaton's ventilated transformers--Types DS-3, DT-3, MD and KT--use a NEMA 2 rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields. Eaton encapsulated--Types EP, EPT, EPZ and EPTZ-- and totally enclosed, nonventilated (Types DS-3E and DT-3E) transformers use a NEMA 3R rated enclosure. Buck-Boost Transformers An autotransformer has only one winding, and is therefore smaller and more economical than the conventional twowinding transformer. In an autotransformer, the primary and secondary are electrically and mechanically connected. The required secondary voltage is obtained by "tapping-off" from the single winding. Buck-boost autotransformers are insulated units with 120 x 240 or 240 x 480 volt primaries and 12/24, 16/32 or 24/48 volt secondaries, and provide a very economical method for minor voltage adjustments where circuit isolation is not needed. Autotransformers can be used only where local electrical codes permit, and isolation of the two circuits is not required. Nonlinear Ratings The transformers shall be specifically designed to supply circuits with a harmonic profile equal to or less than a K-factor of 4 or 13, as described in the following table, without exceeding specified temperature rise. Nonlinear Ratings Harmonic K-4 K-13 Fundamental 100.0% 100.0% 3rd 34.0% 70.0% 5th 22.0% 42.0% 7th 3.0% 5.0% 9th 1.0% 3.0% 11th 0.7% 3.0% 13th 0.5% 1.0% 15th 0.3% 0.7% 17th 0.3% 0.6% transformers and their installation to minimize the potential for sound transmission to surrounding structures and sound reflection. It is suggested that the following installation methods be included: 1. If possible, mount the transformer away from corners of walls or ceilings. For installation that must be near a corner, use soundabsorbing materials on the walls and ceilings if necessary to eliminate reflection. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-20 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher (up to 15 dB greater) due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. 2. Provide a solid foundation for mounting the transformer and then use vibration dampening mounts if not already provided in the transformer. (Eaton encapsulated EP/EPT designs use a special encapsulation system and ventilated DS/DT-3 designs contain a built-in vibration dampening system to minimize and isolate sound transmission.) All Eaton general-purpose dry-type distribution transformers are designed with sound levels lower than NEMA ST-20 maximum levels. However, consideration should be given to the specific location of the 3. Provide flexible conduit to make the connections to the transformer. 4. Locate the transformer as far as possible from areas where high sound levels are undesirable. 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 Average Sound Levels NEMA ST-20 Average Sound Level, dB Equivalent Winding Self-Cooled Ventilated (up to 1.2 kV) kVA Range K-Factor 1, 4, 9 K-Factor 13, 20 Encapsulated (up to 1.2 kV) 3.00 and below 40 40 45 3.01 to 9.00 40 40 45 9.01 to 15.00 45 45 50 15.01 to 30.00 45 45 50 30.01 to 50.00 45 48 50 50.01 to 75.00 50 53 55 75.01 to 112.50 50 53 55 112.51 to 150.00 50 53 55 150.01 to 225.00 55 58 57 225.01 to 300.00 55 58 57 300.01 to 500.00 60 63 59 2 2 2 2 2 2 2 500.01 to 700.00 62 65 61 700.01 to 1000.00 64 67 63 Greater than 1000 Consult factory Consult factory Consult factory Volume 2--Commercial Distribution CA08100003E--April 2019 www.eaton.com 2 V2-T2-171 2 2.6 Transformers Transformer Standards, Technical Data and Accessories 2 Typical Data for General-Purpose Dry-Type Distribution Transformers, Aluminum Wound 1 2 Type EP 115C Rise 2 kVA Weight Lbs Losses in Watts Efficiency Al No Load 1/4 Load Cu Total % Impedance 2 % Regulation 1/2 Load 3/4 Load Full Load 100% P.F. 80% P.F.

The primary safety standard for transient voltage surge suppressors (TVSS) has undergone major revisions in the past three years with mandatory compliance by manufacturers required by September 29, 2009. Even the name of the standard has changed from UL Standard for Safety for Transient Voltage Surge Suppressors, UL 1449 to UL Standard for Safety for Surge Protective Devices, UL 1449. This means that TVSS listed to the UL 1449 2nd Edition standard will no longer be able to be manufactured after September 29, 2009. All Surge Protective Devices must be designed, tested, manufactured and listed to the UL 1449 3rd Edition standard after this date. Isolating transformer: A transformer where the input (primary) windings are not connected to the output (secondary) windings (i.e., electrically isolated). K-factor: A common industry term for the amount of harmonics produced by a given load. The larger the K-factor, the more harmonics that are present. Also used to define a transformer's ability to withstand the additional heating generated by harmonic currents. kVA: Kilovolt-ampere. Designates the output that a transformer can deliver for a specified time at a rated secondary voltage and rated frequency without exceeding the specified temperature rise.

Regulation: Usually expressed as the percent change in output voltage when the load goes from full load to no load. Scott T connection: Connection for three-phase transformers. Instead of using three sets of coils for a three-phase load, the transformer uses only two sets of coils. Series/multiple winding: A winding consisting of two or more sections that can be connected for series operation or multiple (parallel) operation. Also called seriesparallel winding. Short circuit: A low resistance connection, usually accidental, across part of a circuit, resulting in excessive current flow. Primary taps: Taps added to the primary (input) winding. See Tap.

Transformers rated for 60 Hz can be applied to circuits with a higher frequency, as long as the nameplate voltages are not exceeded. The higher the frequency that you apply to a 60 Hz transformer, the less voltage regulation you will have. 60 Hz transformers may be used at lower frequencies but only at reduced voltages corresponding to the reduction in frequency. For example, a 480 to 120 volt 60 Hz transformer can carry rated kVA at 50 Hz but ONLY when applied as a 400 to 100 volt transformer (50/60 x 480 = 400). 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 Can single-phase transformers be used on a three-phase source? Yes. Any single-phase transformer can be used on a three-phase source by connecting the primary terminals of the single-phase transformer to any two wires of a three-phase system. It does not matter whether the three-phase source is threephase three-wire or threephase four-wire. The output of the transformer will be single-phase. Can transformers be used to create three-phase power from a single-phase system? No. Single-phase transformers alone cannot be used to create the phaseshifts required for a threephase system. Phase shifting devices (reactors or capacitors) or phase converters in conjunction with transformers are required to change singlephase power to three-phase. What considerations need to be taken into account when operating transformers at high altitudes? At altitudes greater than 3300 feet (1000 meters), the density of the air is less than at lower elevations. This reduces the ability of the air surrounding a transformer to cool it, so the temperature rise of the transformer is increased. Therefore, when a transformer is being installed at altitudes greater than 3300 feet above sea level, it is necessary to derate the usable capacity of the transformer. The table below lists the derating factors. As an example, a 75 kVA 480V-208Y/120V transformer installed at 10,000 feet needs to be derated by 4%. Instead of 208A output, the usable current is only 199A. Altitude Feet Meters Current Rating Factor 3300 1000 1.00 4000 1200 0.995 5000 1500 0.99 6000 1800 0.985 7000 2100 0.98 8000 2400 0.97 9000 2700 0.965 10,000 3000 0.96 12,000 3600 0.95 14,000 4200 0.935 15,000 4500 0.93 What considerations need to be taken into account when operating transformers where the ambient temperature is high? Eaton's dry-type transformers are designed in accordance with ANSI standards to operate in areas where the average maximum ambient temperature is 40C. For operation in ambient temperatures above 40C, there are two options: Insulation Classes 1. Order a custom designed transformer made for the specific application. Previous Designation Insulation System Rating (C) Class A 105 2. Derate the nameplate kVA of a standard transformer by 8% for each 10C of ambient above 40C. Class B 150 Class F 180 Class H 220 Class R 220 What is the normal life expectancy of a transformer? When a transformer is operated under ANSI/IEEE basic loading conditions ANSI C57.96), its normal life expectancy is 20 years. The ANSI/IEEE basic loading conditions are: A. The transformer is continuously loaded at rated kVA and rated voltages. B. The average temperature of the ambient air during any 24-hour period is equal to 30C and at no time exceeds 40C. C. The altitude where the transformer is installed does not exceed 3300 feet (1000 meters). 2 2 2 2 2 V2-T2-202 What are insulation classes? Insulation classes were originally used to distinguish insulating materials operating at different temperatures. In the past, letters were used for the different designations. Recently, insulation system temperatures (C) have replaced the letters' designations. Volume 2--Commercial Distribution CA08100003E--April 2019 www.eaton.com How do you know if the enclosure temperature is too hot? UL and CSA standards strictly regulate the highest temperature that an enclosure can reach. For ventilated transformers, the temperature of the enclosure should not increase by more than 50C in a 40C ambient at full rated current. For encapsulated transformers, the temperature of the enclosure should not increase by more than 65C in a 25C ambient at full rated current. This means that it is permissible for the temperature of the enclosure to reach 90C (194F). Although this temperature is very warm to the touch, it is within the allowed standards. A thermometer should be used to measure enclosure temperatures, not your hand. Transformers Transformer Standards, Technical Data and Accessories Can transformers be reverseconnected (reverse-fed)? Yes, with limitations. Eaton single-phase transformers rated 3 kVA and larger can be reverse-connected without any loss of kVA capacity or any adverse effects. Transformers rated 2 kVA and below, because there is a turns ratio compensation on the low-voltage winding that adjusts voltage between no load and full load conditions, should not be reverse-fed. Three-phase transformers with either delta-delta or delta-wye configurations can also be reverseconnected for step-up operation. When reversefeeding a delta-wye connected transformer, there are two important considerations to take into account: (1) The neutral is not connected, only the three-phase wires of the wye system are connected, and (2) the ground strap between X0 and the enclosure must be removed. Due to high inrush currents that may be created in these applications, it is recommended that you do not reverse-feed transformers rated more than 75 kVA. The preferred solution is to purchase an Eaton step-up transformer designed specifically for your application. Can transformers be connected in parallel? Yes, with certain restrictions. For single-phase transformers being connected in parallel, the voltages and impedances of the transformers must be equal (impedances must be within 7.5% of each other). For three-phase transformers, the same restrictions apply as for single-phase transformers, plus the phase shift of the transformers must be the same. For example, a deltawye-connected transformer (30 phase shift) must be connected in parallel with another delta-wye-connected transformer, not a delta-delta connected-transformer (0 phase shift). Why is the impedance of a transformer important? The impedance of a transformer is important because it is used to determine the interrupting rating and trip rating of the circuit protection devices on the load or line side of the transformer. To calculate the maximum short circuit current on the load side of a transformer, use the following formula: Maximum Short Circuit = Load Current (Amps) Full Load Current (Amps) Transformer Impedance Full load current for singlephase circuits is: Nameplate Volt-Amps -----------------------------------------------------Load (output) Voltage and for three-phase circuits, the full load current is: Example: For a standard three-phase, 75 kVA transformer, rated 480 volt delta primary and 208Y/ 120 volt secondary (catalog number V48M28T7516) and impedance equal to 5.1%, the full load current is: 2.6 What clearances are required around transformers when they are installed? All dry-type transformers depend upon the circulation of air for cooling; therefore, it is important that the flow of air around a transformer not be impeded. UL 1561 requires that there be no less than 6 inches (152.4 mm) clearance between any side transformer with ventilation openings and any wall or obstruction. In compliance with NEC 450.9, Eaton's ventilated transformers have a note on their nameplates requiring a minimum of 6 inches (152.4 mm) clearance from the ventilation openings and walls or other obstructions. This clearance only addresses the ventilation needs of the transformer. There may be additional local codes and standards that affect installation clearances. 2 2 2 2 2 2 2 2 2 2 2 2 2 Transformers should not be mounted in such a manner that one unit will contribute to the additional heating of another unit, beyond allowable temperature limits, for example, where two units are mounted on a wall one above the other. 2 2 2 2 2 2 The maximum short circuit load current is: 2 208.2A ------------------ = 4,082.4A 0.051 2 The circuit breaker or fuse on the secondary side of this transformer would have to have a minimum interrupting capacity of 4083 amperes at 208 volts. NEMA ST-20. 2 2 2 A similar transformer with lower impedance would require a primary circuit breaker or fuse with a higher interrupting capacity. 2 2 2 2 2 2 Volume 2--Commercial Distribution
