sulphur hexafluoride Transfer for 132kv

Sulphur hexafluoride gas will extinguish the arc as explained earlier. When the gas passes through the arc, then the it reduces the area of cross section of the arc, and we know that, resistance is inversely proportional to the resistance. It means resistance of arc will increase and current will interrupt.
