Abstract—This paper presents the leakage current (LC) on porcelain insulator surface evaluated by the rotating wheel tester. The experiments have been studied under the conditions of severe environmental impact with surface contamination on specimens and then excited by electrical stresses for accelerated aging. The experiments were divided in two cases – high voltage alternating current and impulse excitation voltage. The result of the experiments showed that the LC on surface of specimen in both cases gradually increases almost exactly the same results for the first 100 cycles after that it rapidly increases with rotating wheel more than 100 cycles.
