1. A system for detecting a falling conductor in a power transmission or distribution system comprising:

  • a conductor carrying voltage,an electrical measurement device in electrical communication with the conductor to measure an electrical characteristic of the conductor at a location in the power transmission or distribution system to determine whether the measured electrical characteristic is indicative of the conductor separating from the power transmission or distribution system;

    a communication device to send a signature indicative of the falling conductor to a control device; and

    wherein the control device is programmed to send a signal to activate one or more switching devices to deenergize the falling conductor in a time before the conductor contacts a ground surface.
