BREAKER FLASHOVER 1(2)
The detection of the breaker flashover is based on the following condition:
1. Breaker open,
2. Voltage drop measured from either side of the breaker during the flashover period,
3. Voltage difference drop, and
4. Measured flashover current through the breaker.
Furthermore, the scheme is applicable for cases where either one or two sets of three-phase voltages are available across
the breaker.
