500kV Electric Discharge at Power Station

The potential between two lines is 500kV, that's half a megavolt! At these potentials the air molecules get ionized and the air transfers electricity creating an impressive electric discharge.

The video was taken at Eldorado Substation in Boulder City, NV.
