Analysis for Power Frequency Electric Field of 500kV ehv Transmission Lines

Hu Yan

Abstract

Calculation model called equivalent electric charge is used to estimate the distribution of electric field below Ehv transmission lines,besides,difference between with aerial landlines or not are also briefly introduced.Through the simulation of MATLAB software for a practical 500kV transmission line,its surrounding electric field characteristic is analyzed in the paper.Aiming at ehv transmission lines whether be into operation or not,it puts forward several different ways to reduce electric intensity,and it can be provided reference for reducing power frequency electric field of 500kV transmission line.
