75+ pages current interruption in ac circuit breaker 3mb. In this method the resistance kept low until current is zero. This property of ac circuit is exploited for interruption purposes and the current is not allowed to rise again after a zero occurs. At current zero the space between contacts is deionized quickly by. Read also breaker and learn more manual guide in current interruption in ac circuit breaker The arc is interrupted by suitable insulator and technique.
Just before second current zero the arc forms cylindrical shape under the magnetic field for CO 2 gas unlike SF 6. 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.

The circuit breakers are used to break electric power.
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. 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. The rated breaking capacity Icu or Icn is the maximum fault-current a circuit-breaker can successfully interrupt without being damaged. 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. Numerical results show that applying the magnetic field induces swirl flow which leads to the pressure rise in the puffer chamber for both gases. The circuit breakers are used to break electric power.
