Why Do Transmission Line Failure Cause a Disproportionate Amount of the Wildfires in California

12/30/19

“Why is it that transmission line failures cause ten times more wildfires than they should in California?”

 

Transmission line failures have the ability to start wildfires, as in the case of Paradise. However, In California, while these accidents are responsible for starting only around 1% of fires they cause 10% of all damage (Mitchell, 2013)!  This is because these transmission lines failures are more likely to occur during periods of high winds and low humidity, which are ripe for wildfires. So when they do occur, they’re much more likely to spin out of control. This is Why Transmission Line Failure Cause a Disproportionate Amount of the Wildfires in California.
