Why power flickers in severe weather. ⚡

Typically a tree limb will hit a power line, which causes a short and a surge at substation which causes an auto resetting breaker to trip. If it’s a small enough limb , the voltage will burn up the limb or the force of the electricity will repel the limb.

Back at the substation auto resetting breaker will reclose and try again a few times to test if the momentary fault is corrected before finally shutting down the line until a technician can clear the fault.
