		abstract={Power breaker (PMT) is a switch that is used to connect or disconnect electric power under normal conditions or in abnormal conditions or disturbances. To always be able to maintain the reliability of PMT, it is necessary to carry out regular maintenance. This study aims to identify the working principle of the PMT transformer 1, what tests were carried out on the PMT and to recognize the reliability and feasibility of the Power Breaker (PMT). Collecting data in this study using direct, indirect, and interview methods. In the analysis of this study, using data from the maintenance of Power Breakers (PMT) in the maintenance of this 2 (two) year period, it also analyzes the maintenance of the previous period in 2021 using the interview method. While in 2022 using the direct method. This calculation method is carried out to obtain data from the PMT test results. Then perform data processing whether PMT is still feasible to work well or not. With reference to the data analysis method, the results of calculating the leakage current on the insulation resistance So far, the test is still according to the specified standard (VDE Catalog 228). kV = 1mA. Shows that PMT still has good insulation resistance. Meanwhile, the contact resistance and simultaneous resistance are still in accordance with the standard SPLN 1.1995 ? 3.3) 100 . Which shows good results, the resistance is below 50 . While the results of the 2022 ground resistance are in accordance with the standards specified, by the SPLN 1.1995 ? 3.3 standard, which is less than 1 so the tested PMT is still feasible to operate. However, if it cannot be ascertained that it is absolutely 100% connected to earth, then the standard test is made for the maximum resistance or resistance in the grounding cable to earth, which is standard below 2 ohms or below 1 ohm.}
