Abstract
Power Breaker (PMT) is a switch that is used to connect or disconnect electrical power in normal conditions or in abnormal conditions or disturbances. To always maintain the reliability of the PMT, regular maintenance needs to be carried out. This writing aims to identify the working principles of the PMT bay 7AB3, what tests are carried out on the PMT and identify the reliability and suitability of the Power Breaker (PMT). In this writing analysis, data from Power Breaker Maintenance (PMT) results during the 2 (two) yearly maintenance period for 2022 are used and compared with the minimum standards set. The results of the analysis state that in testing the grounding resistance for the R, S, T phases is 0.5Ω; 0.4Ω; 0.7Ω and the difference in simultaneous resistance time for open time condition 1 is 0.9 ms, open time condition 2 is 0.65 ms and closing time condition is 2.15 ms. In the contact resistance test, the value for phase R was 39.1 µΩ; S phase of 36.7 µΩ; phase T is 20.7 µΩ where this value is in accordance with the permitted standard, namely.
