GE IS200EPCTG1AAA Exciter PT/CT Terminal Board

IS200EPCTG1AAA Exciter PT/CT Terminal Board

The IS200EPCTG1AAA Exciter PT/CT (EPCT) terminal board contains isolation transformers for critical generator voltage and current measurements. Two 3-phase generator potential transformer (PT) voltage inputs are input to EPCT as shown in the following diagram, EPCT Terminal Board. Two generator current transformer (CT) inputs, with current levels of 1 A or 5 A, are input. All the isolation transformer output signals are cabled to the EMIO board in the control rack. In addition, one analog input, which can be either a voltage or current, is brought into EPCT. When the highest reliability is required, three EPCT boards can be used.

Generator Voltage and Current Measurement

· The generator voltages from the customer is potential transformers are wired through switches to TB1. The cable lengths can be up to 1000 ft of #12 AWG wire. The PT inputs are nominally 115 V rms at 50/60 Hz and are fused. On EPCT, two isolation transformers make a three-wire open delta voltage measurement, yielding 1.533 V rms for a 115 V rms input.

· Two generator current inputs from the CTs are wired to non-pluggable terminal blocks, TB2 and TB3. Each current transformer has a 0-1 A rms winding and a 0-5 A rms winding, but only one is wired to EPCT. The cable length from the transformer to the EPCT board can be up to 1000 ft., and the wire gage can be up to #10 AWG.

EPCT provides four voltage test points (TP9-12), one on each leg of the secondary side of the generator current isolation transformers. These should not be grounded through the measuring device.
