Effect of Shielding Lines on Power Frequency Electric Field under Overhead Lines

Abstract:

This paper discusses effect of shielding lines on reduction of electric field produced by overhead lines. Charge simulation method is used. Influences of height, space and number of shielding lines on electric field are calculated. Space between shielding lines has reverse roles on influencing area and maximal electric field. Number and space of shielding lines should be carefully selected to shielding a certain area. Analytical method is also used to express induced electric field by shielding lines. Result of comparison with charge simulation method shows that it is suitable for area outside of three phase lines.
