IS200EACFG2A GE EX2100, Exciter AC Feedback Board

Description:

The IS200EACFG2A is an Exciter AC Feedback Board developed by GE. The IS200EACF Exciter Ac Feedback board (EACF) measures the exciter PPT ac supply voltage and current. The terminal board contains transformers for a three-phase voltage measurement, and terminals for two Flux/Air core coils. The outputs of the voltage and current circuits are fanned out to three DB9 connectors for cables to controllers M1, M2, and C. The cable between EACF and the EBKP backplane board can be up to 90 m in length.The EACF board is located in the exciter auxiliary cabinet.

High frequency noise suppression near the point of signal entry is provided for the flux/air core input signals. Cable shield terminal screws attached to chassis ground are located within three inches of the input screws where applicable.

Exciter Voltage Measurement
The IS200EACFG2A version supports a single three-phase input voltage in the nominal range up to 1000 V rms +20% at 50/60 Hz.
The potential transformers on both boards supply a nominal 1.6 V rms from their secondary outputs.

Air Core CT/Flux Coil Inputs
The air core current transformers deliver a nominal secondary output voltage in the
range 0 to 0.8 V rms at 50/60 Hz.
