It can prevent a relative impact flashover caused by lightning overvoltage from turning into a stable power frequency arc, greatly reducing the arcing rate and the number of trips of the circuit breaker
It can make a relative impact flash caused by lightning overvoltage not turn into a stable frequency arc, greatly reduce the arc-building rate and trip times of circuit breakers
It can make a phase to ground impulse flashover caused by lightning overvoltage not change into stable power frequency arc, and greatly reduce arc building rate and tripping times of circuit breaker<br>
