75+ pages current interruption in ac circuit breaker 2.3mb. This synthetic alternating current can then be interrupted using a conventional AC circuit breaker. 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. High current cause severe mechanical stress on many components in the transmission or distribution systems eg. Check also: breaker and understand more manual guide in current interruption in ac circuit breaker In AC circuit breakers arc interruption is simpler because the current is alternating and has values of zero in every cycle where it is easier to interrupt.
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. In high resistance method the arc resistance is made to increase gradually with the time so that the current force in between the two contacts is insufficient to maintain the arc.

DC power is used because it allows for a battery bank to supply closetrip power to the breaker control circuits in the event of a complete AC power.
In ac Circuit-breakers the arc is interrupted at a current zero. Circuit-breakers having instantaneous current interrupting capability current-limiting AC circuit breakers also can be used in AC networks to eliminate the peak current at short-circuits. This method is applicable only in ac circuit interruption because there is natural zero of current 100 times in a second for 50 Hz 3-phase supply system. Initially when the contacts are pulled apart an electric arcing plasma forms. Therefore the main problem in a circuit breaker is to. When the contacts are far enough apart.
