Utility equipment eyed as a possible source of fire near L.A.

LOS ANGELES — Federal investigators are looking into whether a huge wildfire near Los Angeles was sparked by Southern California Edison utility equipment, according to the company.

Edison has turned over a section of an overhead conductor from its transmission facility in the area where the Bobcat Fire started more than two weeks ago, company spokesman David Song said Wednesday.

The initial report of fire was near Cogswell Dam in the San Gabriel Mountains at 12:21 p.m. on Sept. 6.

In an incident report filed with the state Public Utilities Commission last week, Edison said its nearby equipment experienced an issue five minutes earlier, 12:16 p.m.

A circuit at a nearby substation experienced a “relay operation,” indicating its equipment detected some kind of disturbance or event, Song said.

Cameras captured smoke developing in the area around 12:10 p.m., prior to the activity on Edison’s circuit, he said.

Edison will assist the U.S. Forest Service in its investigation of the fire that has burned more than two dozen homes and other buildings on its way to becoming one of the largest blazes in Los Angeles County history.
