2. The program reprocesses continuously that if there is load shed eg sensor detects no voltage then it
turns on the relay and it gets to the other terminal relay. Thus if r phase is load shed then it connects to
the y phase and there is electricity in r phase if now electricity come in the r phase then relay is switched
off and the relay returns to normal state. This process is
