What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?
Exception: may be a precursor to the accident, has not yet caused the loss, the cause is unknown,Such as the normal operation of the cable overheating, burning plastic taste
Obstacles: not clear, probably not normal and must be modified to be normal,If the circuit breaker parameter is not appropriate, change the parameter specification.
Fault: operation is not normal, simple inspection process can be restored in time,Such as the use of electric leakage, overload caused by leakage circuit breaker trip.
Accident: has occurred, resulting in loss of damage,Such as short circuit arc circuit breaker tripping, burning, scrap.
