Abstract
This article investigates the characteristics of cap and pin glass insulator and its enhancement due to contamination particles or elements by means of laboratory experiments. The insulator surface is simulated for dry conditions as well as its changes under wet conditions. To find the influence of the contamination layers on the leakage current and voltage distribution, various levels of the ESDD of the insulators were applied in the study. Additionally, experimental results show that the higher contamination level of insulator may have lower breakdown voltage especially in wet condition.
