Therefore, the distribution of electrical energy from substations to consumers is strived to be stable. Substation is part of the electric power transmission system to lower voltage, one of the equipment is a power breaker (PMT) that serves as a switch used to connect and disconnect electric power in a loading state. To keep the tool functioning properly, maintenance is carried out periodically. At the time of maintenance of this PMT was carried out several tests such as contact prisoner testing, isolation testing, testing of land enforcement prisoners and pmt contact seismicity tests. This study was conducted by comparing pmt test results data with the last few testing periods. The research was conducted on pmt BTP refiners at tello substation. The method used is observation, interview, documentation, with the title taken. After the collection of references then continued with the retrieval of research data obtained by following procedures from the agency. The next stage analyzes the changes that occurred in pmt in the last 3 years of annual maintenance.} }
