Method and Device for Remote Determination of the Distance to the Place of Damage to the Insulation of Cables of Power Lines

A method for determining the location of damage to the insulation of power lines cables or communication line cables is proposed. The wires of a damaged cable communication line or power electric cable of various classes of AC and DC voltage as elements of a multipolar electric circuit of the “star” type are considered. A structural diagram of the developed device is presented, and a theoretical evidence of the developed method for measuring the distance to the place of damage to the insulation of communication cable or power transmission cables is given. Equations for calculating the distance to the place of cable insulation damage are obtained. The results of an experimental verification of the developed method and device for measuring the distance to the place of damage to the cable insulation are presented.
