GE IS200EPCTG1A Exciter PT/CT Terminal Board

Product Introduction

The GE IS200EPCTG1A is a PT/CT Terminal Board designed to operate within the GE Mark VI and Mark VIe Excitation Control Systems, specifically within high-reliability environments where precise monitoring of current and voltage is essential. This board plays a critical role in interfacing with both Potential Transformers (PTs) and Current Transformers (CTs), providing safe and accurate signal conditioning, termination, and routing for input to the control system.

It is engineered to connect high-voltage and high-current instrument transformer signals to protection and control electronics within the excitation system. By handling both analog signal scaling and isolation, the IS200EPCTG1A ensures the integrity and accuracy of real-time generator measurements used for excitation control and protection.

With its robust design and dependable terminal architecture, this board is widely deployed in power generation environments, from traditional thermal plants to hydroelectric and renewable sources. Its modularity, ease of installation, and stable performance make it an ideal choice for both new installations and retrofit applications.
