Southern California Edison, a unit of utility Edison International , said on Monday preliminary analysis of data showed a "momentary and expected increase in current" on its energized lines in the Eaton Canyon corridor on Jan.

Southern California Edison has reported a Jan. 7 fault on a power line that was connected miles away from the lines located near the origin of the deadly Eaton Fire that sparked that day.

High-voltage power lines saw a temporary surge in electrical current in the area where the deadly Eaton Fire is believed to have started, Southern California Edison said.

Edison says current increase "remained within the design limits and operating criteria" for the circuits and "did not trigger system protection on these lines."
