Product Description

The IS200EGDMH1A model is an exciter field ground detector module, which is what the functional abbreviation of EGDM stands for. During installation, this module will mount in the exciter power backplane rack and will be in proximity to the EPSM module. This module operates on a simplex and redundant system, the simplex system requires one EGDM, while a redundant system requires three EGDM modules. The IS200EGDMH1A is used in conjunction with an EXAM module, together these two modules work to ascertain the potential of field ground leakages on any point of the DC or AC side.

IS200EGDMH1A GE EX2100 Exciter Field Ground Detector Board

When the EGDM module and DSPX module are attached through fiber-optic cables, the EGDM module will send the voltage that has been used over to the DSPX module through the fiber-optics; after this process has occurred the voltage will then be checked, and alarms will be attached by the DSPX. The EGDM module has three LED indicators on the faceplate. The three indicators on the IS200EGDMH1A module are a power indicator, an active indicator, and a selective master indicator.

One of the best ways to identify this module is through the alphanumeric catalog number that is directly printed on the board, but there is also a small plate on the bottom of the faceplate that indicates what the module is. 

Frequently Asked Questions about IS200EGDMH1A

How is the EXAM module used with the EGDM module?

One of the ways that the EXAM module works is by sensing the voltage across the ground resistor and will then send the signal to the EGDM through a nine-conductor cable.

If the IS200EGDMH1A board is used in a redundant system how are the three boards configured?

If the EGDM board is used in a redundant system the three boards will be configured as a Controller (C), Master 1 (M1), and Master 2 (M2). The configuration for each EGDM is controlled by a set of program pins on the P2 connector.

Is the IS200EGDMH1A model an active system?

Yes! As an active system, the EGDM model will apply a voltage to the field circuit.

What does the EGDM model do?

There are numerous functions of the EGDM model, one of them being to detect field leakage resistance between any point in the field circuit of the ground and the generator.
