The purpose of this research is to find out the comparison of the results of the insulation resistance test, contact resistance and leakage current dulfur, to find out the test results are in accordance with the standards and to carry out maintenance if they produce values that do not match the standards used. The data analysis method used is by comparing the calculations with the test results in accordance with the standards used by PLN or not. The results of the insulation resistance test according to the dulfur gadung test standard after cleaning the R phase the result is 164 M?, the S phase is 119 M?, and the T phase is 170 M?. The dulfur LRT test after replacing the insulator with the results of the R phase was 9.5 G?, the S phase was 2.68 G?, and the T phase was 5.27 G?. The results of the insulation resistance test that do not meet the standards in the dulfur test before cleaning the S and T phases produce a value of 0. The contact resistance test results in a value that does not meet the standard for the busbar test, B phase R, the result is 168 µ?, the S phase is 188 µ?, and the T phase is the result. 186 µ?. The current leakage test results meet the standard, busbar B testing in the R, S and T phases with a value of 0.03 mA.} }
