Answer / raghavendran.r

I would like to add more on the previous answer.As stated
earlier trip circuit supervision relay will monitor the
proper functioning of trip circuits based on the feedback
signal obatained from the tripped circuit.if the circuit
has not tripped even after getting trip command,then as a
preventve measure sometimes LBB ie local breaker back up
will act upon to prevent any further damage to the system
due to any fault.

Answer / hanuman

trip circuit supervision relay is the relay which
supervises the trip circuit of the circuit breaker. It even
tests wheather dc supply to trip circuit is under proper
condition or not. some times trip circuit gives signal to
circuit breaker, but circuit breaker doesn't break the
circuit, then supervision relay makes circuit to break by
LBB.
