Many and various faults such in rural country side overhead high voltage distribution cables that in windy conditions blow into adjacent trees and a high voltage auto - re close circuit breaker trips out for a few seconds, then re sets. Or an underground distribution cable fault caused by accidental damage maybe an excavator or a worker with a pneumatic pick..Or maybe an overload on the low voltage side causes a circuit breaker to trip out. The reliability and heavy engineering construction of modern HV switchgear precludes equipment fault in only the rarest occurrence.

Well, the most recent time, it was somebody trying to steal the copper tehre.
