MARTINSBURG, W.Va. - A transformer that failed Wednesday afternoon at Allegheny Power's Martinsburg substation caused a utility service outage that affected about 1,700 customers for several hours, a company spokesman said.
The failure first was reported to Allegheny Power at 1:18 p.m., and spokesman David Neurohr said "everybody was back on" by 4:30 p.m.
The transformer failed because of a fault in another piece of equipment, causing a chain reaction, Neurohr said.
The outage appeared to affect multiple blocks of King and John streets, but Neurohr could not specify the exact area.
The City of Martinsburg had stop signs placed at downtown intersections where traffic signals were not working.
Security personnel in the lobby of the federal courthouse building at 217 W. King St. said access was "limited" because of the outage.
Though it didn't affect the electricity supply to the courthouse and annex, deputy clerks for Berkeley County Clerk John W. Small Jr. said their computer systems were disabled by the power failure.
