Detailed data

GE IS200EGDMH1AFG Exciter Ground Detector Module

It is a two-slot, double-height form factor circuit board that is mounted in the exciter power backplane rack. The excitation ground detector detects the excitation leakage resistance between any point in the generator excitation circuit and ground, either on the AC or DC side. A simplex system will have one EGDM and a redundant system will have three. The EXAM is an attenuator module that senses the voltage across the ground sense resistor and sends the signal to the EGDM through a nine-conductor cable. The EXAM module is mounted in the high voltage module in the auxiliary panel. The signal conditioner receives the attenuated differential signal from the sense resistor in the EXAM module. The signal conditioner is a simple unity gain differential amplifier with a high common mode rejection ratio followed by an A-D converter. The VCO powers the fiber optic transmitter. The signal conditioner can measure the output level of the power amplifier by grounding the bridge side of the attenuated sense resistor on command from the control section.

Frequently asked questions about the product are as follows:

-What is the purpose of the IS200EGDMH1AFG module?
It monitors the generator excitation system for ground faults, which can indicate insulation breakdown or other electrical problems.

-What are the common symptoms of a faulty ground detector module?
False alarms of ground faults or no alarms when a fault occurs. Inconsistent readings or erratic behavior in the excitation system. Burnt or discolored components.

-How do I troubleshoot a IS200EGDMH1AFG module?
Check wiring and connections for damage or loose connections. Use a multimeter or oscilloscope to verify input and output signals.
