Critical flashover voltage
WebJun 23, 2024 · Minimum insulator flashover Voltage (FOVmin) During each test, the failure voltage of the insulator continuously decreases as the leachates in the pollutant are dissolved due to the moisture. These leachates make the insulator become more and more conductive until a flashover occurs (Lambeth 1988 ). WebOct 29, 2024 · This voltage doubling effect (i.e. traveling wave theory) will likely cause the breaker insulator to flashover resulting in yet another path for current to flow to ground. The voltage doubling effect can also occur if the breaker is open during operation to break the power frequency fault back at the tower.
