Economic pressures have led to the increasing application of condition-based maintenance to high-voltage AC (HVAC) circuit breakers. The effort of condition monitoring is not justified for every circuit-breaker type, however, and may depend on its importance to the reliability and availability of the system, its maintenance program, and its expected workload. Practically speaking, it is important to frequently switched breakers, such as live-tank breakers that switch shunt capacitors and… CONTINUE READING
