gis sf6 storage System for sustainability and safetyWhat Is An Arc?Arc in Circuit BreakerThermal Ionization of GasIonization Due to Electron CollisionDeionization of GasRole of Arc in Circuit BreakerArc Interruption Or Arc Quenching Or Arc Extinction TheoryDuring opening of current carrying contacts in a circuit breaker the medium in between opening contacts become highly ionized through which the interrupting current gets low resistive path and continues to flow through this path even the contacts are physically separated. During the flowing of current from one contact to other the path becomes so heated that it glows. This is called arc.See more on electrical4uEstimated Reading Time: 10 minsWhat are Circuit Breakers?
