Edison of Southern California said in a regulatory filing Thursday it is investigating the possibility of a discontinued electrical circuit running parallel to the high-voltage transmission line above the Altadena.
“SCE is assessing many potential causes, including whether the idle mesa-Silmer transmission line could be lively,” said in an update sent to the California Utilities Commission. .
Invalid Mesa – Sylmer Line extends the miles through the Angeles National Forest and ends with a metal tower adjacent to two large towers. This was determined by the ridge where fire investigators determined to be the origin of the Eton fire. It was just after 6pm on January 7th.
New cell phone video clips obtained from public sources by NBC Los Angeles will be recorded at 6:14pm from a different location than most other videos at the first moment of the fire, and will display the flame directly. It looks like it’s not a new, tall tower that lived a 220,000 volt transmission line under an abolished tower.
“You don’t think that a deactivated line will come back to life,” said electrical engineer Ken Bush.
He said that inductive electricity on the dead mesa-Silmer line is not dangerous as long as it is grounded properly, but if the ground connection is not appropriate or deteriorated, it is a source of heat and sparks It said it could be at a tower near where the fire began.
“Induced currents can lead to poor connections, so you can have an arc that will cause fire if the line is dead and the ground is not appropriate,” Bush said.
Edison raised the possibility in Thursday’s filing, exploring the induction phenomenon, saying, “… there is a certain degree of possibility that that line or its grounding may be related to the cause of the fire.”
SCE said in a document that it inspected the Mesa-Sylmar line every year between 2020 and 2024, with photos taken before and after the fire being “obvious” and “obvious” that ignites the tower and arcing. “He said he had no signs. M16T1. ”
“SCE will learn more if we can more closely examine the equipment related to the M16T1 structure, including the laboratory environment,” he said.
Mesa – Another tower at the other end of the Silmer line shows “other signs of damage to two grounding devices, two of the three idle conductors,” but It is not known when the damage occurred.
SCE said last month it did not detect faults or anomalies on the Eton Canyon high-voltage transmission line 12 hours before the Eton Fire was fired.
The company faces dozens of lawsuits from fire victims who argue that Edison should be responsible for causing the fire.
