There is a question about whether there was contact with the power carrying wires in the topic event.
It is possible that no such contact occurred, but unlikely. The metal extension of the wooden pole is tall, and bent over enough, that he plane may to be out of contact. In the dynamics of the event, the lane almost certainly swung into the power wires, resulting in the line protection ground detection relays tripping the breaker feeding the line, and then swung free. The relays and breaker trips for ground faults are very fast, and the damage to the plane might be trivial, or severe, depending on which portion of the plane came in contact first. The plane seems to be in contact with one of the high voltage power cables, in addition to the grounded static wire, so the feeder relays should have re-tripped, and locked out the feeder.
If the feeder was re-closed, with the plane out of contact, it would stay energized, providing a trap for any one trying to get the pilot down, unless they called the power company and arranged for the power to be turned off.
By contrast, if a plane comes down on two conductors, not a ground, the relays that trip the breaker are set 10 to 100 times as high as the ground relays, and substantial damage is sure to result.
Regardless, the wise pilot remains seat belted in place until rescuers are there, with proper equipment to get him down.
A Ripley's "Believe it or not" that happened at our power company many years ago, a plane made a sliding contact with a 230,000 volt line, leaving visible paint on the conductor, and causing a ground fault trip. The plane was red and white. The surrounding area was searched, first on the ground, then from the air, and no sign of a wrecked plane was found. No plane was reported missing, and no one reported damage to their plane. We have no idea how that plane completed a circuit from the line to ground, passed enough current to trip the line, and was still flyable. The paint seemed most likely to have come from a wing, as the surface the paint came from was smooth. Somebody was amazing lucky.
