Use the SEL-311L Relay with integral four-zone distance backup for easy-to-apply, high-speed line protection.
IEC structuring is hierarchical in nature. For example if switchboard =N-A1 contains a circuit breaker -Q1 then the full designation of the circuit
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.
Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of
