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

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.
