PRODUCT INFORMATION
Product Overview
The General Electric IS200EGDMH1A is an exciter field ground detector module designed for Mark VI and Mark VIe systems. This module carries the functional abbreviation EGDM within the EX2100 excitation control architecture. It mounts directly into the exciter power backplane rack and operates near the EPSM power supply module. Simplex system architectures utilize a single EGDM module for monitoring. Redundant system configurations deploy three identical EGDM modules to maintain protection coverage.
The IS200EGDMH1A module operates in conjunction with an EXAM module to detect field ground leakages. Together, these modules ascertain ground leakage potentials across points on either the AC or DC circuits. Fiber-optic cables link the EGDM module directly to an associated DSPX digital signal processor module. The EGDM transmits measurement voltages across fiber optics to the DSPX for alarm evaluation and processing. Faceplate diagnostic indicators include power, active, and selective master status light-emitting diodes.
