Protection Relay:Types, wiring diagram and working principle.

Protection relay is an electromechanical monitoring safety device which senses fault and provide trip signal to the breaker as per set value in LT and HT panel.

Power System Protective Relays: Principles & Practices

As the protected components of the electrical systems have changed in size, configuration and their critical roles in the power system supply, some protection aspects need to be revisited (i.e. the use of
