High winds caused 69,000-volt power lines along the Williams to Grand Canyon line to touch and overload a circuit Sunday afternoon, leading to a hourlong power outage the entire length of Route 64.
According to Grand Canyon's APS representative Don Keil, it's not uncommon for power lines to slap together in the wind, causing lights to flicker as a circuit breaker opens and closes.
But when they touch for more than about five seconds, the breaker doesn't close when the lines separate. Then APS crews must go out and locate the problem. This one was found at the Williams substation.
