IS200EGDMH1A Exciter Ground Detector Module Mark VI system GE Turbine Control

Product Details:

IS200EGDMH1A is an Exciter Ground Detector Module manufactured and designed by General Electric as part of the EX2100 Series used in Excitation Control Systems. It mounts in the Exciter Power Backplane rack as a double slot, double height (6U) form factor board (EPBP).

The field ground detector measures the resistance in the field between any point in the field circuit of the generator and the ground, whether it is on the ac or dc side. A redundant system will have three EGDMs, but a simplex system will have one. Figure 1 displays the position of the EGDM(s). In order to communicate with the EGDM(s), EXAM, the attenuator module, measures the voltage across the ground sensing resistor.The High Voltage Module, which is housed in the Auxiliary Panel, has the EXAM module mounted in it.
