Partial discharge disturbances can be tested to see whether the discharge is good or bad on the SKTM which is indicated by partial discharge. Among them are cable system inspections and PD mapping. The number of partial discharge disturbances in SKTM occurs due to poor jointing or other impacts such as dredging of the cable which causes voids. The research was conducted at the Lenteng Agung customer service unit which had several disturbances which were dominated by partial discharge disturbances in jointing. This study aims to determine the effect of partial discharge disturbance on the reliability of the UP3 Lenteng Agung feeder and to understand the test and calculation value of Partial discharge (PD) with parameters PDmax [pC] and PDLevel [pC]. The analytical method used in this research is quantitative analysis method. The test method for data collection is the 20 kV cable assessment method. The results showed that partial discharge is the most frequent disturbance and affects the reliability of the feeder with 9 disturbances caused by partial discharge in the jointing. and the results of the analysis of the condition of the Mertua feeder cable being alert with an estimated maintenance of 1 year with the conclusion of the analysis based on the PDIV and PDEV voltage discharges and the discharge of the load on the cable as large as and the condition of the Tambourine feeder in poor status with an estimated maintenance of 6 months.} }
