GE IS200EDEXG1A Exciter De-Excitation Board

Product Introduction

The GE IS200EDEXG1A Exciter De-Excitation Board is a specialized control module designed for use within the GE Mark VI and EX2100 excitation control systems. This board is responsible for managing the de-excitation process of synchronous generators, which involves controlled reduction of the generator field current to safely and effectively decrease generator excitation.

De-excitation is a critical function for protecting the generator and associated equipment during shutdown, fault conditions, or transitions in operating modes. The IS200EDEXG1A board ensures the de-excitation signal is accurately generated and delivered to the excitation system, enabling a controlled ramp down of field voltage and current.

This board is built to industrial standards with robust components, designed to withstand the electrical and thermal stresses encountered in power generation environments. It integrates seamlessly with GE’s digital excitation platforms, ensuring reliable performance and system protection.
