what is trip circuit supervision relay? How does it work in
switchgear?
Answer Posted / 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.
