NStar crews seek cause of brief power outage in Cambridge

By Lauren Dezenski, Globe Correspondent

It’s not clear what caused 5,000 NStar customers to briefly lose power in Cambridge this morning, NStar spokesman Mike Durand said.

The power went out at 9:45 a.m., though service was restored to all customers at about 10:15 a.m., Durand said. Crews are investigating an issue on a nearby transmission line as a possible cause, he said.

In a message posted on Twitter, Cambridge police said officers helped to direct traffic at intersections with inoperative signals in East Cambridge.
