Product Overview – IS200EGDMH1A
Brand / Series / Model Classification
| Item | Description |
|---|---|
| Brand | GE (General Electric) / GE Fanuc |
| Series | EX2100 Excitation Control System |
| Full Model Name | IS200EGDMH1A – Exciter Field Ground Detector Module |
Product Description
The IS200EGDMH1A is a Field Ground Detector Module designed for use within the EX2100 excitation system, typically installed in power generation facilities. It plays a critical role in monitoring ground faults in the exciter field circuits, both AC and DC.
It works in conjunction with an Attenuator Module (EXAM), receiving attenuated voltage signals from the exciter field ground path and analyzing them to determine whether a ground fault has occurred. Its function is essential for preventing equipment damage due to insulation failures or grounding problems.

FAQ – IS200EGDMH1A
Q1: Does IS200EGDMH1A require the EXAM module to function?
A: Yes. The EGDM relies on the EXAM module to measure ground path voltage. EXAM attenuates this voltage and sends it to EGDM for ground fault analysis.
Q2: How many EGDM modules are needed in a redundant system?
A: Three modules are used—one Controller and two Masters (Master1 and Master2) to ensure fault tolerance. The modules are configured using programming pins.
Q3: Can this module be used in a simplex (non-redundant) system?
A: Yes, a single EGDM module is sufficient for simplex setups, but redundancy enhances system reliability.
Q4: What is the detectable resistance range for ground faults?
A: The module can detect ground resistance in the range of 0 to 200 kΩ.
Q5: How fast does the module respond to a detected fault?
A: It reacts in under 10 milliseconds, which is fast enough for real-time protective actions.
Q6: Is it suitable for extreme temperature environments?
A: Yes. It operates in a wide range from –30°C to +65°C, ideal for industrial and utility applications.
Q7: What should I check if the “Active” LED is off?
A: It could mean the module is not selected as Master, it’s not receiving input from EXAM, or it’s not properly installed. Verify wiring and system configuration.
Q8: Will its weight or size affect panel installation?
A: Not at all. Weighing approximately 0.467 kg and sized for standard 6U racks, it fits comfortably in existing EPBP racks.
Q9: Does it support monitoring of both AC and DC excitation systems?
A: Yes. It can monitor both types of fields for ground faults.
Q10: What should I do before replacing this module?
A: Ensure:
-
It’s the correct model
-
Jumper settings are properly configured
-
All fiber optic and signal connections are correct
-
Power is disconnected before handling
-
The new module is installed securely into the EPBP rack
