Description
Product Introduction
This GE F31X185PTAHG1 is a current transformer (CT) interface board for GE’s excitation and power conversion control platforms. The “PTA” designation identifies this as a Potential Transformer board, but in this context it provides current transformer signal conditioning for generator excitation systems.
The board interfaces with current transformers to measure generator and bus currents. It provides signal conditioning, isolation, and protection for the measurement circuits. The board is essential for current feedback, protection, and control functions in generator excitation systems.
