Abstract :
This final project research was conducted on 150 kV PMT equipment at the West Surabaya substation. A power breaker is an important piece of equipment in a substation, because if there is a disturbance or short circuit, the PMT can cut off the voltage in order to protect other equipment in the event of a disturbance. In this study, data collection was carried out by field observation by conducting several tests on isolation prisoners, contact prisoners, grounding prisoners, contact forging. Then conduct a literature study by studying reference books as a guide to analyze the results of tests that have been carried out. After testing the results of the grounding resistance testing in each phase, which is 0.2 ?. In contact resistance testing the values of each phase were 8.03 ??, 20.42 ??, 8.81 ??. In the test the forging of contacts at the time of open 35.8 ms, 36.6 ms, 35.7ms. And at close 63.4 ms, 63.2 ms, 63.1 ms. Then on the insulation resistance at the top-ground point 53 G?, 69 G?, 65 G?. Ground bottom point 356 G?, 425 G?, 266 G?. Top-bottom points 325 G?, 369 G?, 452 G?. In the overall test on this PMT, the value still meets the standards, so it can be said that the PMT 150 kV bay Tandes 2 is in good condition and fit for operation
