Four common fault type cable tray:
The first type of fault: the whole cable is burned or a phase was burned, the fault caused by the electric current relay action on the power distribution cabinet, the cable in the fault is very serious damage.
Second kinds of faults: cable each phase is short circuit, the same, the fault caused by the power distribution cabinet on the current relay and voltage relay are all action, cable in the fault point is also very serious damage
Third kinds of failures: cable tray only one phase circuit breaker, current relay, fault point of light damage but show obvious. May be the phase current is too large or caused by cable quality.
Fourth types of failures: cable internal short-circuit, the appearance of the traces, such a failure is generally due to cable quality caused by the relatively rare.
