The main purpose of this paper was that to compare design of post insulators and their performance of different post insulator the relative performance of different insulator materials used in substation as lightning arrester, current transformer and potential transformer. Insulators are used to protect from the dangerous effects of electricity flowing through conductors. This paper presents the role of post insulators are key components of most electrical substation equipment and their features and ability are changing due to the difference type of electrical power incoming line and pollution level of their rating. The peak voltage rating of each arrester at 132 kV is 118.6 kV, creepage distance is 2904 mm and maximum continuous operating voltage is 94.88 kV. The creepage distance of current transformer and potential transformer at 132 kV are 4065 mm. Therefore, in this paper, the effects of material changes, rating changes, pollution level changes of lightning arrester, current transformer and potential transformer in substation are described. Then, analysis and discussion of lightning arrester and instrument transformer are described in this paper.
