The Composition and the Electrical Characteristics of Natural and Artificial Contaminants

In this paper, we investigate the electrical characteristics of contaminants on highvoltage insulators. We measure the conductivity of polluted water obtained from bottom surface of insulators with wiping method with wiping method, then calculate the equivalent salt deposit density(ESDD) with specific equation. And, through the analysis, ICP/MS, for contaminants, we can know the amount of specific composition which is contained in the washed solution. Based on the analysis result, we investigated the degree of contribution on the electrical characteristics of contaminant solution. Through this investigation, we got some significant result, such as the relationship between the conductivity and solubility.
