GE IS200EGDMH1ABC Ground Fault Detection Module for Excitation Systems
Description
GE IS200EGDMH1ABC is a ground fault detection module designed for excitation systems, part of GE’s EX2100 series excitation control system and a component of the Mark VI Speedtronic series for heavy gas and steam turbine management. It detects ground faults in exciter field circuits, provides accurate ground impedance measurements, and works with EXAM attenuator modules to monitor leakage current on both AC and DC sides of field circuits.
