PLN (PERSERO) UP3 BINJAI}, year={2023}, url={http://156.67.221.169/5964/}, abstract={This thesis aims to evaluate the characteristics of polymer, glass, and ceramic insulation in the 20 kV Medium Voltage (MV) Overhead Lines of PT. PLN (Persero) UP3 Binjai. The research is conducted because the insulation quality in MV Overhead Lines plays a crucial role in maintaining the reliability of the power system. The evaluation is carried out through visual inspection, leakage current test, flashover voltage, and insulation resistance tests on samples of polymer, glass, and ceramic insulation that have been in operation within the network for a specific period. This research adopts an experimental approach by taking samples from several locations within the 20 kV MV Overhead Lines network. The research findings indicate that the polymer, glass, and ceramic insulation in the 20 kV MV Overhead Lines of PT. PLN (Persero) UP3 Binjai still meet the established standards. Although there is a slight decline in the performance of some insulation samples that have been in operation within the network for a certain period, they remain within safe limits and can function effectively. This research is expected to provide a deeper understanding of the insulation conditions in the 20 kV MV Overhead Lines network, enabling PT. PLN (Persero) UP3 Binjai to take appropriate preventive measures or maintenance actions to uphold the reliability and performance of their power system.} }
