DRY TYPE TRANSFORMERS

General Information

Single Phase

Type EP Encapsulated

Type EP general purpose transformers are single phase, resin

encapsulated designs suitable for

indoor or outdoor applications. Its

totally-enclosed, non-ventilated

enclosure make it ideally suited for

use in areas that contain dust,

moisture, or corrosive fumes.

Available in ratings through 25 kVA &

4160 volts, type EP transformers can

be mounted in any position for indoor

installations and in upright positions

only for outdoor installations.

Three Phase

Type EPT Encapsulated

Type EPT resin encapsulated, 3-

phase transformers are available in

ratings of 3-75 kVA, up to 4160V

primary. Its totally enclosed nonventilated enclosure makes the EPT

ideally suited for outdoor as well as

indoor locations. Type EPT transfon mers utilize the 185°C insulation

system with 115°C rise.

Units installed outdoors must be

mounted in upright position.

General Information

Industry Standards

All Cutler-Hammer dry-type distribution and control transformers are built

and tested in accordance with applicable NEMA, ANSI and IEEE standards.

All 600 volt class transformers are UL listed unless otherwise noted.

Seismic Qualified

The Cutler-Hammer family of dry-type distribution transformers is seismically

tested, seismically qualified and exceeds requirements of the Uniform

Building Code (UBC) and California Code Title 24.

Frequency

Cutler-Hammer standard dry-type distribution transformers are designed for

60 Hertz operation. Transformers required for other frequencies must be

specifically designed.

Overload Capability

Short term overload is designed into transformers as required by ANSI.

Basically, 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 preceeids 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 & Temperature Rise

Industry standards classify insulation systems and rise as shown below:

Insulation System Classification

Ambient Winding Hot Temp.

Rise Spot Class

40°C 55°C 10°C 105°C

Series-Multiple Windings

Series-multiple windings consist of 2 similar coils in each winding which can

be connected in series or parallel (multiple). Transformers with seriesmultiple windings are designated with an "X" or "/" between the voltage

ratings, such as primary voltage of "120/240" or "240 X 480". If the seriesmultiple winding is designated by an "X', the winding can be connected

only fora 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.

DRY TYPE TRANSFORMERS 

Genera/Information 

Single Phaae 

Type EP Encapsulated 

Type EP general purpose transformers are single phase, resin 

encapsulated designs suitable for 

indoor or outdoor applications. Its 

totally-enclosed, non-ventilated 

enclosure make it ideally suited for 

use in areas that contain dust. 

moisture, or corrosive fumes. 

Available in ratings through 25 kVA & 

4160 volts, type EP transformers can 

be mounted in any position for indoor 

installations and in upright positions 

only for outdoor installations. 

General Information 

Industry Standards 

Three Pha •• Type EPT Encapsulated 

Type EPT resin encapsulated, 3-

phase transformers are available in 

ratings of 3-75 kV A. up to 4160V 

primary. Its totally enclosed nonventilated enclosure makes the EPT 

ideally suited for outdoor as well as 

indoor locations. Type EPT transformers utilize the 185°C insulation 

system with 115°C rise. 

Units installed outdoors must be 

mounted in upright position. 

All Cutler-Hammer dry-type distribution and control transfonners are built 

and tested in accordance with applicable NEMA. ANSI and IEEE standards. 

All 600 volt class transformers are UL listed unless otherwise noted. 

Seismic Qualified 

The Cutler-Hammer family of dry-type distribution transformers is seismically 

tested, seismically qualified and exceeds requirements of the Uniform 

Building Code (UBC) and California Code Title 24. 

Frequency 

Cutler-Hammer standard dry-type distribution transformers are designed for 

60 Hertz operation. Transformers required for other frequencies must be 

specifically designed. 

Overload Capability 

Short term overload is designed into transformers as required by ANSI. 

Basically, dry-type distribution transformers will deliver 200% nameplate load 

for one-half hour; 150% load for onlHlour; and 125% load for fou~-hours 

without being damaged provided that a constant 50% load preceeds and 

follows the overload. See ANSI C57 .9&{)1.250 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.

I

Specialty harmonic cancellation transformers with multiple secondary outputs for

mission critical applications . They are ideally suited for electrical systems where the

electronic equipment loads ( personal computers ...) are similar and they can be

divided equally among the outputs.

APPLICATION

The PowerStarTM T3000 and T4000 are recommended for critical test environments and to

support electronic equipment that generates a complex spectrum of harmonic currents. These

harmonic currents can result in excessive heating and voltage distortion. These issues can

cause numerous op rational problems for the electrical 4ystem and the electronic equipment

connected to it. Wh e over-sizing or k-rating the electrical system can withstand the extra

heating, the Powers tarTM T3000 and T4000 designs treat 3rd 5th 7th 9th 11th, 1 J, 15th

harmonic currents and address both the extra heating and voltage distortion. In addition, its

high efficiency design typically achieves a 50% reduction in energy losses when compared to

conventional transformers.

APPLYING The PowerStarTM T3000 and T4000

These transformers perform optimally when installed close to the 3-phase, 4-wire panelboards

that feed the equipment circuits. They can be installed a the end of a long run, however the

loads must be lanced and matched to achieve optimu harmonic cancellation. The T3000

is more sensitive to this last requirement. See PowerSta TM Application Handbook for details.
