Abstract :
This paper discusses influence of sloping ground on electric field under overhead lines. Sloping ground is first transformed into flat ground by use of conformal mapping. Then the analytical expression of electric field is obtained by mirror method. The calculation method of electric field with sloping ground is verified by an example with analytical result. At last, electric field under overhead lines with varying slope angle and distance from sloping ground to overhead line is calculated to show their influences.
