insulating gas Circuit Breakers - Construction, Types and Working

The high-pressure flow of sulphur hexafluoride gas (insulating gas) rapidly absorbs the free electrons in the arc path. It forms immobile negative ions which are ineffective as charge carriers. The result is that the medium between the contacts quickly builds up high dielectric strength and causes the extinction of the arc.Get price
