  • Recommended circuit breaker tests - Megger

    It is important that the moisture content inside an SF6 breaker is kept to a minimum as it can cause corrosion and flashovers inside the breaker. When there is arcing (i.e., faults or normal interruptions) inside of the circuit breaker, the SF6 combines with water to produce corrosive by-products. Air pressure test; applicable for air-blast breakers. Air pressure level, pressure drop rate and air flow are measured
