advantages of sulfur hexafluoride monitoring

Advantages: The time of Arcing is very less as the Sulfur hexafluoride gas quickly absorb the arc electrons. As the dielectric strength of Sulfur hexafluoride gas is very high so this circuit breaker can interrupt a large amount of current. There is no risk of fire. As the whole chamber closed tightly there is no moisture problem. Low maintenance cost.
