Description

The IS200EPCTG1A is a specialized Exciter Potential Transformer (PT) and Current Transformer (CT) Terminal Board designed for the General Electric EX2100 excitation control system. This interface module acts as a critical bridge between the generator's high-voltage sensing circuits and the EX2100 control rack. By providing a secure, ruggedized termination point, the board facilitates the accurate acquisition of voltage and current feedback signals necessary for precise generator regulation and grid stability.

Features

• Designed specifically for the GE EX2100 excitation control system.
• Provides high-voltage isolation and signal conditioning for PT and CT secondary inputs.
• Integrated surge suppression and EMI filtering to protect sensitive downstream digital electronics.
• Optimized for high-density cabinet mounting with efficient cable management.
• Supports reliable operation in demanding industrial environments including thermal and hydroelectric power plants.

Applications

This terminal board is utilized in power generation facilities to manage generator excitation control. It is essential for systems requiring high-availability feedback loops for voltage regulation, current monitoring, and protective relaying within the EX2100 architecture.
