Abstract
Abstract In this paper an analytic model allowing simulating the electrical characteristics and the leakage current of a snow‐covered insulator is proposed. For that purpose, leakage current through a snow‐covered insulator was monitored under high alternative voltage at a temperature of −12°C. From the measured voltage–current characteristics, it was found that the voltage across snow and the leakage current flowing through the snow‐covered insulator were almost in the same phase. However, the resistance of snow was found to be non‐linear, as it decreases with an increase in voltage across snow. Based on the experimental results, a mathematical model enabling to simulate the leakage current was elaborated. This model shows that the leakage current through snow can be expressed as an exponential function of the voltage across snow, depending on the density and conductivity of the water melted from the snow. The comparison of results obtained by the analytical model and those by experiment shows a good correlation. Copyright © 2007 John Wiley & Sons, Ltd.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
