IS200EXAMG1BAA GE Module Parts Exciter Attenuation Module

The GE IS200EXAMG1BAA is an Exciter Attenuation Module (EXAM) manufactured by General Electric (GE), designed for use in the GE EX2100 and EX2100e excitation control systems. The module plays a critical role in the generator field ground detection system, working in conjunction with the Exciter Ground Detector Module (EGDM) to monitor potential ground faults in the generator excitation circuit.

The IS200EXAMG1BAA provides high-voltage signal attenuation and conditioning, reducing exciter field voltage signals to suitable levels for ground fault detection and processing. It is typically installed in the High Voltage Interface (HVI) module within the auxiliary cabinet, supporting reliable excitation system operation and helping protect generator equipment against insulation-related faults.

• Reduces high-voltage excitation signals to usable measurement levels.
• Provides signal conditioning for the ground detection circuit.
• Helps protect sensitive electronic components.
