Description
The GE IS200EGDMH1AFG is an exciter grounding detection module designed specifically for GE excitation control systems. This module detects leakage resistance between the generator excitation circuit and ground, whether on the AC or DC side.

The GE IS200EGDMH1AFG is a precision exciter ground detection module engineered by General Electric for use in excitation control systems such as the EX2100 and Mark VI/Mark VIe turbine control platforms. This module plays a critical role in monitoring insulation integrity and detecting ground faults within the generator’s field circuit, helping protect synchronous generators, excitation systems, and connected equipment from damage caused by insulation breakdown or unintended grounding.

Designed to be installed in the Exciter Power Backplane Rack (EPBP) of GE’s excitation control system, the IS200EGDMH1AFG continuously evaluates the resistance between any point in the generator field winding and earth ground. It injects a controlled ±50 V square‑wave test signal into the field circuit and measures leakage current to determine whether the field winding insulation exceeds safe resistance thresholds.

If a ground fault is detected, the module sends a fault signal to the system controller, enabling protective alarms or automatic shutdown actions to prevent severe electrical faults or unplanned outages.
