Current Interruption In Ac Circuit Breaker 35+ Pages Explanation [725kb] - Latest Update
70+ pages current interruption in ac circuit breaker 1.4mb. The circuit breakers are used to break electric power. This property of ac circuit is exploited for interruption purposes and the current is not allowed to rise again after a zero occurs. Normally the value of Icu for Miniature Circuit Breaker MCB is. Check also: interruption and understand more manual guide in current interruption in ac circuit breaker Therefore the main problem in a circuit breaker is to.
Initially when the contacts are pulled apart an electric arcing plasma forms. This transient voltage is known as restriking voltageThe current interruption in the circuit depends upon this voltageIf the restriking voltage rises more rapidly than the dielectric strength of the medium between the contacts the arc will persist for another half cycleOn the other hand if the dielectric strength of the medium builds up more rapidly than the restriking voltage the arc fails to restrike and the current will.

This method is applicable only in AC circuit interruption because there are natural zero of current 100 times in a second for 50Hz three-phase supply system.
This synthetic alternating current can then be interrupted using a conventional AC circuit breaker. The production of arc may delay the current interruption process and generate emormous heat which may cause serious damage to system or to circuit breaker itself. There are two methods of extinguishing thearc in circuit breakers. Why DC supply is used in circuit breaker. The main task of a circuit breaker is to interrupt fault currents and to isolate faulted parts of the system. The probability of such a current occurring is extremely low and in normal circumstances the fault-currents are considerably less than the rated breaking capacity Icu of the CB.
