Abstract
A lightning protection or internal surge device designed to suppress surges on electrical transmission or distribution lines by expending some of the excess energy in the form of corona discharge in both wet and dry conditions. The device is a very thin (of diameter not exceeding 0.1 mm) conducting wire, fiber, filament, or a bundle of such filaments, or a yarn or woven or knitted fabric made of such fibers or wires which is wound around a live conductor or ground wire forming a coil. When the coil is exposed to the fields created by the voltage surges on the line or ground wire it enhances corona losses on the line thereby damping/suppressing the surges as well as prolonging the front time of the surge to reduce its steepness.
Claims8
A lightning or internal surge protection device for suppressing surges on an electrical conductor line of an electrical transmission or distribution network, comprising:
- pulse-less corona producing conductors wound around the electrical conductor line and forming coils, each pulse-less corona producing conductor having a diameter not exceeding 0.1 mm for reducing a corona inception voltage of the electrical conductor line upon which each conductor is wound, in both dry and wet conditions.
A method of making a lightning or internal surge protection device for suppressing surges on an electrical conductor line of an electrical transmission or distribution network, comprising a step of:
- winding pulse-less corona producing conductors around the electrical conductor line to form coils, each pulse-less corona producing conductor having a diameter not exceeding 0.1 mm for reducing a corona inception voltage of the electrical conductor line upon which each conductor is wound, in both dry and wet conditions.
