System Architecture & Signal Flow
The TRM01 board interfaces between transformer current/voltage transducers and the UNITROL excitation controller’s main processing unit. It conditions analog signals from PT/CT inputs, performs scaling and filtering, and outputs standardized signals to the controller bus. This architecture ensures that transformer thermal, voltage, and current parameters are accurately represented in the excitation control loop, enabling precise AVR (Automatic Voltage Regulator) response and transformer protection coordination.
