Technical Parameters
Functional Acronym: EGDM (Exciter Ground Detector Module)
Model Implementation: GE IS200EGDMH1AGG
Injection Signal: ± 50 V square‐wave, current‐limited to 80 mA nominal
Test Modes:
Normal Test: 5 s interval
Fast Test: 400 ms interval for rapid fault confirmation
Measurement Range: Detects insulation resistance paths down to < 1 kΩ
Output Characteristic: Low source impedance (< 1 Ω) to force fault current
Power Supply: Draws from VME backplane 5 V and 12 V rails
Operating Temp: -30 °C to +65 °C
Storage Temp: -40 °C to +85 °C
Humidity: Up to 95 % RH, non‐condensing
Product function
The GE IS200EGDMH1AGG module injects a controlled test waveform into the generator’s field winding and monitors the return current to detect insulation-to-ground faults. It provides both periodic self‐tests and on‐demand fast scans, issuing a "ground‐fault" signal to the EX2100 controller when leakage exceeds preset thresholds—enabling timely alarms or shutdowns to protect generator windings.
Core supporting modules
EXAM Attenuator Module: Interfaces measurement signals between the GE IS200EGDMH1AGG and EX2100 controller.
High‐Voltage Power Module: Supplies excitation voltage during ground‐fault tests triggered by the EGDM.
EX2100 Controller: Aggregates GE IS200EGDMH1AGG fault flags for display and trip logic.
Extension components
Redundancy Kits: Mounting hardware and jumpers for multi-GE IS200EGDMH1AGG installations.
Field‐Wiring Harnesses: Custom cables terminating at GE IS200EGDMH1AGG test points.
Replacement Bezel: Faceplate with status LEDs for GE IS200EGDMH1AGG identification.
Rack Mounting Kits: VME chassis accessories compatible with the GE IS200EGDMH1AGG.
Software support
Configuration: Thresholds/intervals set in EX2100 software; GE IS200EGDMH1AGG operates as hardware endpoint.
Diagnostics: GE IS200EGDMH1AGG status flags reported via EX2100 HMI.
Integration: Native support in GE systems; no driver updates needed for GE IS200EGDMH1AGG.
