NSFW Language Warning

This short video by Huw Griffiths has gone viral after being featured on Reddit

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  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.”
