Abstract As a special weather condition, fog-haze has widely public attention. A temporary fog-haze chamber is built in this paper, kaolin particle with medium diameter of 2.5μm and (NH4)2SO4 resolutions are adopted to simulate the fog-haze. The corona loss experiments are performed in different fog-haze densities. The obtained artificial simulated particle diameter and fog-haze density are similar to that of real fog-haze. The corona loss experiments in different fog-haze densities show that: The corona loss grows in a shape of power function with the increase of electric field intensity. Moreover, with the augment of fog-haze density around the transmission lines, the corresponding corona loss also increase, but the increment is not significant.
