Product Feature

Field Ground Detection: GE IS200EGDMH1ADE works chiefly as an exciter ground detector module. Detection of field leakage from the AC and DC sides of the field circuit: The control system can detect field leakage from both the AC and DC sides of the field circuit, which is important for ensuring the safety and stability of the excitation system.

General Features Redundant System Support: Redundant Control system with 3 GE IS200EGDMH1ADE boards in which controller, master 1 and master 2 are configured. This redundancy builds robustness and stability into the system so it can keep going, even if one of the boards fails.

Signal Processing and Transmission: It operates together with a board EXAM that allows us to compute the voltage on the pin of ground sensing resistor. It is then passed as a signal to a related module like the DSPX module using EISB in the controller rack that uses Fiber-optic link.

Multi-LEDs: The front face-plate of the board has several indicators: main power indicator, activity indicator and master selection indication. The integration of these lights plays a vital role in understanding the operational state of the module at a glance, thus aiding in monitoring and ensuring smooth collaboration.

Installation

Mounting: GE IS200EGDMH1ADE is located in the exciter power backplane rack. The three EGDM boards in a redundant architecture should be mounted in the appropriate slots and correctly connected to the backplane. A backplane consists of two connectors; these two backplane connectors on the board need to be properly connected to the corresponding backplane interfaces. The connection needs to be secure in order to transmit the signal correctly.

Troubleshooting

To avoid this: No Power Indication To check whether the power supply circuit is normal, the power cable is connected properly, whether there is a problem with the power supply voltage. And that the boards internal power supply module is not damaged.

In case of Abnormal Indicator Lights: Check status of the activity indicator or this master selection indicator is abnormal, please first check whether the board and other related module connection is normal. This also could be caused by a loose connection or issue with the signal transmission cable. Next, see if the board's configuration settings are in order.

Fault if the module can not well detect the field ground leakage and through GE IS200EGDMH1ADE, you can verify whether this EXAM board work is normal, whether GE IS200EGDMH1ADE and EXAM board work in a connected state. Also check if there is any faults with the ground sensing resistor and related signal conditioning circuits.

Communication Interface Problem: If there is no communication, check the communication line, especially fiber communication line between it and DSPX module. Do not break the fiber-optic cable, communication parameters should make the right.

Application range

Energy Power Generation Industry: GE IS200EGDMH1ADE is mainly used in gas turbine generator units and steam turbine generator units. This allows it to play an essential role in monitoring and protecting the excitation system of a generator, ensuring the generator's safe operation and the quality of the power supply.

Marine Plant: This module is also applicable to gas or steam turbines from marine power plants or large marine propulsion systems to guarantee the reliable operation of the turbine excitation system in the marine environment.
