GE IS200EXAMG1BAA Excitation machine attenuation module
Specific parameters
Circuit board specifications: The four corners of the circuit board are drilled by the factory for installation, and the edges are surrounded by insulating material.
Electrical connection: There are two female connectors, including a 3-pin female plug (J1) and a 9-pin female cable connector (J2, also labeled as “ground detector”). The circuit board also has a screw connection (TB1) for surface wiring, three jumper switches, and two tab on connectors (labeled E1 (V-Bus-P) and E2 (V-Bus-N)).
Circuit components: including two metal oxide varistors, one relay, four polyester ethylene capacitors, twenty wire wound resistors, and resistors made of other materials.
Product Performance
The IS200EXAMG1BAA module works in conjunction with the EGDM board as a field grounding detector to protect the generator shaft of the system. It can detect any grounding path that may exist in the exciter components, and achieve this function by applying a low-frequency AC voltage relative to ground to the electrical center of the excitation winding.
