The disconnection of the pantograph

Added	Thu, 06/10/2016
Феномены	UFO
Version type	Technical devices

In AC locomotives when lowering the pantograph (current collector) is heard a sharp sound similar to cotton. It's the sound from the sudden release of compressed air "blow out" the electric arc (it is formed at the time of separation of a pantograph from the contact network).
Eyewitnesses sometimes associate it with the explosion of the ball lightning, or even with an explosion or a UFO landing, etc.
