Working of Project:Introduction of Relay:A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal or where several circuits must be controlled by one signal.
Working:We are connecting two Sources one is KESC and second is UPS. KESC is connected with
Normally Open of the relay and Coil terminal and UPS is connected with Normally Close of the relay. When
