Instrument Transformer, Div of GE 3P3 Data Sheet

GE

Energy Connections

Model 3P3

Current Transformer
Window Diameter 0.97”

Application

3 phase metering and other switchboard
applications and for current to voltage
conversion by use of a loading resistor as
illustrated in the graph below and having
low primary current input.

Frequency

50-400 Hz.

Insulation Level

600 Volts, 10 kV BIL full wave.

Continuous Thermal Current
Rating Factor

Models 3P3-500 - 3P3-301:

1.33 at at 30°C ambient.

1.0 at 55°C ambient.

Models 3P3-1000T:
450 A at 30°C amb., 300 A at 55°C amb.,

Terminals are brass studs No. 8-32
with one flatwasher, lockwasher and
regular nut.

Transformers can be ordered with
secondary leads configured in various
ways (consult factory).

Load resistors may be mounted directly
on terminals thus providing a “space
saver” feature.

Approximate weight 1.75 lbs.

Model 3P3

The graph illustrates voltage output capacity,
and over the ranges shown, will maintain
± 3% linearity.
