I care about plasma! Plasma is why a temporary fault on a power line (a lightning strike is a common instigator) has to be cleared by disconnecting the line. The lightning is long gone, but the overvoltage it caused creates a plasma arc that is sustained by the line voltage. Do I have that right? I'm a utility electrical engineer.
