NSFW Language Warning
During a windy night, a power-line issue occurred, causing a giant electrical fireball to travel down the lines and explode!
Never has swearing been more appropriate.
Electrical engineer BeesKnees21 explains that the fireball is actually “a high impedance electrical arcing fault. They can start because of tree branches or animals or lightning strikes or anything that can bridge two phases or a phase and ground. The air becomes ionized and no longer acts as an insulator but a conductor.”
