IS200EACFG1B

The IS200EACFG1B is an AC Feedback EX2100 Board developed by GE. The Exciter AC Feedback board (EACF) in the EX2100 Excitation Control measures the exciter PPT AC supply voltage and current.

Application Data

The phase voltage output from potential transformers is measured using voltage test rings TP1-4 as follows:

• Measure the Phase to Phase (or Line) Voltage AB between TP1 and TP2.
• Measure Phase to Phase Voltage BC between TP3 and TP4.
• Measure the Phase to Phase Voltage CA between TP4 and TP1.

IS200EACFG1B Board Replacement

• Static-sensitive handling procedures should be implemented on all boards to prevent component damage caused by static electricity. When handling boards or components, use a wrist grounding strap only after they have been removed from potentially electrified equipment and are at a normally grounded workplace. Static sensitive handling procedures should be implemented on all boards to prevent component damage caused by static electricity.
• When handling boards or components, use a wrist grounding strap only after they have been removed from potentially electrified equipment and are at a normally grounded workplace.
• Turn off the power to the exciter, then test the board for power before touching it or any related circuits to avoid electric shock. Remove, insert, or change board connections while power is provided to the equipment to avoid equipment damage.
