A Faraday cage is an enclosure formed by a conducting material that protects a person inside. The cage directs current around the object in the middle, effectively insulating it from the dangers of the electrical current. The air surrounding the person acts like an insulator, as long as they don’t touch the mesh that composes the cage they should be perfectly safe. A car works as a Faraday cage when it is struck by lightning, as does the aluminum body of an aircraft. It also creates a stunning effect, especially when combined with the gigantic Tesla coil you see in the photo. The video below shows high voltage cable inspection using a helicopter and a man in a Faraday cage, as long as the helicopter isn’t grounded they can be raised to the same electrical potential as the wire but have no current pass through them, so they are at no risk. Incredible.
