hence isolate the faulty part of the system from other
normal system.

Answer / muhammed quraish
Relay is a part of protective device used in cojunction
with the circuit breaker in power system protection
applications. It can detect the fault when the operating
current flowing through the relay coil exceeds the pick up
value. But it cannot directly isolate the circuit instead
its action will lead to circuit breaker to operate and will
isolate the circuit in case of a fault.

Answer / sanjay dalvi
Relay is a sensing device....which sence the abnormal
condition,when a fault current flows thrugh it,it gives a
tripping comaand to the circuit breaker....
& circuit breaker is the only device which is use to
isolate the system from faulty pa

Answer / muthuelectric
it is a protective device used to protect the device or
system during fault conditions
| Is This Answer Correct ? | 7 Yes | 7 No |
relay is a sensing device.
when the fault occurs more current flows thro the relay coil
produces sufficient field to attract circuit breaker
contacts,so that ckt is opened
