what is TCS AND MASTER TRIP REALY

Question

Accepted Answer

TCS and Master Trip Relay are protective devices used in electrical systems to prevent damage during faults.

TCS stands for Time Current Characteristic Relay, which operates based on the relationship between time and current to trip the circuit breaker during faults.
Master Trip Relay is a relay that receives signals from various protective relays and initiates a trip signal to disconnect the circuit in case of a fault.
Both TCS and Master Trip Relay play a crucial role in ensuring the safety and protection of electrical systems.
Example: TCS relay can be set to trip the circuit breaker if the current exceeds a certain threshold for a specified time duration.
Example: Master Trip Relay can coordinate the tripping of multiple circuit breakers in a power system to isolate the faulted section.
