		abstract={In this study is analyzing the leakage current and discharge voltage as well as the characteristics of porcelain pin post insulators due to the influence of weather modeling and pollutants. It is known that the pollutants tested were salt, dust, and moss. The weather modeling tested is normal and rainy. When there are pollutants and rain, it can cause a conductive layer on the surface of the insulator so that an electric current can flow through the surface of the insulator which is called leakage current. The method used are withstand and discharge test. The results of this study pollutant and water conductivity level affect the surface of the insulator so that it affects the value of leakage current and discharge voltage. In the withstand test, the insulator resistance was tested at 20 kV with 60 seconds under normal and rain with salt pollutants unable to withstand leakage currents of 0.74 mA and 0.75 mA. In the discharge test of the pin post insulator, the lowest discharge voltage in normal conditions with salt pollutants and rain with salt pollutants with values of 21.79 kV and 21.056 kV and leakage current values of 0.912 mA and 0.892 mA.}
