An underground cable explosion dislodged a manhole cover and briefly knocked out power this afternoon to about 1,000 customers in the Powelton Village section of West Philadelphia, PECO said.
No injuries were reported, but traffic backed up in the area as traffic lights went dark for up to a half-hour.
Liz Williamson, a PECO spokeswoman, said the cable failed about 12:10 in a manhole on Powelton Avenue and 38th Street near Presbyterian Hospital.
The hospital did not lose power.
Williamson said the 1,000 customers who did lose electricity were back on line as of 12:38 p.m.
A Peco crew remained at the scene throughout the afternoon to repair the damaged cable.
