Parts of West Dover and a section of Division Street lost power around 1 a.m. on Tuesday night. The outage was caused by a failed lightning arrestor, a device which absorbs lighting strikes, said Stephen A. Enss, director of the City of Dover Electric Department.
"Occasionally if an arrestor has taken enough shocks it will fail," Enss said. "This one failed. It's a pretty rare occurrence I've only seen it happen about three times in 25 years."
One line crew and one substation crew were dispatched to restore power. The majority of customers had their powered restored before 2 a.m. but some customers in South West Dover didn't have power again until between 3:30 a.m. and 3:45 a.m.
"I would consider this a pretty small outage," Enss said.
