• We investigated a negative creeping discharge traveling over the surface of insulated power cable under an applied lightning impulse voltage. The developing aspect of discharges was observed in detail using a camera equipped with an image intensifier and a high-speed image converter camera. In this paper, it is shown that the distinctive discharge with a positive polarity appears to a normal direction from the cable surface at the applied voltage more than ∼ 90 kVpeak. Negative creeping discharges are extended longer exponentially by the presence of such the positive discharge. The developing mechanism of the creeping discharge is discussed qualitatively based on the experimental results.
