Abstract: This paper presents the results of tests conducted to verify the effect of the voltage source on the critical flashover voltage of dc insulators under pollution. Tests were performed under 3 pollution levels using voltage sources with different voltage drop x leakage current characteristics. A data acquisition system was used to record all current pulses above a certain pre selected current level and the corresponding voltage evolution during current pulse duration, which made possible a complete analysis of …
