12V, 2amps rating at secondary is considered and these three parameters are carried over this
small transformer. This transformer is known as TUT (Transformer under Test).The main
station sends a request to the transformer unit through the RF transmitter module. The
transformer unit receives the request through the RF receiver module, and it sends the
currently monitored parameters of the transformer to the main station through the RF
transmitter module. The values are compared with the preset values in the main station, if
excess in any parameter occurs the main station sends a shutdown signal to the substation.
The substation shuts down the TUT and sends the currently measured parameters to the main
station.
