OPPD can stop surges that enter electrical, telephone and coaxial cable lines. Surges can even be caused by high winds, animal interference and broken tree limbs on lines, traffic accidents involving utility poles, lightning and other disturbances. While surges from lightning strikes often destroy equipment, power surges usually create minor damage that goes unnoticed. Over time, surges can shorten the life of equipment. Computer chips built into today's smart appliances and electronic equipment are particularly vulnerable to surges.
