Calculation of Surface Electric Fields on the Lighting Conductors near HVDC Transmission Lines

Abstract

Corona discharge may occurs when the lighting conductors are close to the HVDC transmission lines. In this paper, the ion flow electric field on the surface of lighting conductors is calculated by flux tracing method. According to the calculated results, influences of the height, radius and distance of lighting lines on surface electric field are discussed, and the approaches to reduce the electric field strength is given.
