Abstract Mixed-phase ice will make conductor surface extremely rough which leads the electric field distorted seriously. The domestic and foreign scientists had done much research on icing conductor, but they always neglecting that operation conductor energized icing and scaled wire was applied to study actual line, even there has been no in-depth analysis of how energized mixed-phase icing influents corona onset voltage. As to explorer effect law, a series AC corona test of single, double and triple bundle conductors were implemented in the artificial climate chamber, UV imaging technology and I-U curve fitting were applied to analyze inception voltage, and then established the finite element model to analyze the distortion rule of conductor surface electric field. Results show that energized mixed-phase ice can cause the inception voltage value down above 50% significantly, Icing in diverse electric field makes different corona onset voltages. As the icing time increase, corona onset voltage will decrease continually, but it will gradually become saturated. In the same icing time, the bundle conductors with more sub-conductors will obtain the higher corona onset voltage. Icing morphology and the corona inception voltage dose not vary with the difference of the freezing-water conductivity. Icicle growing longer and sharper will make electric field distorted more and more seriously. The conclusion of this paper can provide selection reference and onset voltage calculation for the overhead transmission line in mixed-phase iced area.

Key words： bundle conductor energized mixed-phase ice corona inception voltage conductivity UV imaging
