Abstract :
Using a triangular ice sample, the present paper investigated the distribution and the variation laws of the leakage current on an ice surface. In particular, this paper examined the influence of water-film thickness, its conductivity and the surrounding air temperature on leakage current and on surface conductivity of ice. The maximum thickness and the conductivity of the water film on the surface of the vertical ice samples and the corresponding ESDD were also determined
