Protective Relay : Working, Types, Circuit & Its Applications
A protective relay is used to protect the device once the fault is detected within a system. Once the fault is detected, the fault location is found and then provides the tripping signal to the circuit breaker or CB.
Construction of Transformer and its working Principle
The transformer is a static device in its construction and the principle behind the working of transformer is Faraday''s law of Electromagnetic Induction.
