Abstract

Abstract: Corona loss is the major component of transmission line’s power loss and is affected by the wire’s surface roughness. The paper investigates the effect of metal particles with different shapes and sizes on the corona and describes the areas in which metal particles may cause corona. The effect of particles on the corona loss can be reflected in terms of the area’s sizes. The study shows that the electric field intensity around the line will increase significantly when there are metal particles adhering to the line. Comparing the particles of given shapes indicates that the cubic particle have a significant influence on the corona loss and the hemispherical metal particles of a certain radius cause the largest corona loss.

Key words: transmission line, corona loss, finite element analysis, ansoft maxwell, metal particles, corona, electric field intersity
