Arcing at high voltages (24,000,000 volts) - Apparently, this phenomenon was videoed at a substation owned by Edison south of Boulder City, Nevada, near Las Vegas.
The crews had been having trouble exercising the switchgear, and had begun taping work in this station to document problems, if and as they occurred. When the mechanical switch didn't open properly, the resulting phenomenon that you see is called a Jacob's ladder. The arcing discharge continues until there is not enough current to continue "feeding" the growing arc, the arc is too large to sustain, or a breaker or other such safety device in the system trips. thereby cutting the current.
