The influence of fog-haze on AC corona loss of overheadtransmission line conductor

As a special weather condition, fog-haze has widely public attention.A temporary fog-haze chamber is built in this paper, kaolin particlewith medium diameter of and resolutions areadopted to simulate the fog-haze. The corona loss experiments areperformed in different fog-haze densities. The obtained artificialsimulated particle diameter and fog-haze density are similar to that ofreal fog-haze. The corona loss experiments in different fog-hazedensities show that: The corona loss grows in a shape of powerfunction with the increase of electric field intensity. Moreover, withthe augment of fog-haze density around the transmission lines, thecorresponding corona loss also increase, but the increment is notsignificant
