Fault Clearance Ultra Sensing Electronic Circuit Breaker

Abstract As Electrical equipments are more sensible, it has to protect them from high current, short circuit occurance. For tripping, fuse, relays and circuit breakers are employed to safeguard the power system components and circuits as well. Due to existence of sensitive components, much attention is taken to care about the protecting system. This paper explains the protection of equipments using suitable circuit breaker. Ultra fast acting electronic circuit breaker(UFECB) is designed to act as an over current protection device. Circuit breakers like fuse or miniature breakers are preferred for breaking the circuit once short circuit is occurred. In case, when overload fault occurs, the time of tripping is slow and which depends on percentage of overload. For instant fault clearance, tripping mechanism is activated for sensitive loads[1]. Time taken for the tripping mechanism is also considered in a great manner for breaking and making the circuit at short instant.
