Analisis Partial Discharge Pada Saluran Kabel Tegangan Menengah Menggunakan Metode Oscillating Wave Test System

---

ABSTRACT
Partial Discharge (PD) is an early indicator of insulation degradation in medium-voltage cables, which may lead to severe failures in the power distribution system if not detected at an early stage. This study aims to analyze the condition of 20 kV medium-voltage cable lines using the Oscillating Wave Test System (OWTS) method based on a Damped Alternating Current (DAC) voltage source. Measurements were conducted on three cable segments in the area of the State Electricity Company (PLN) in Jakarta, namely segments G1–G2, G3–G4, and G5–G6. The parameters measured include the Partial Discharge Inception Voltage (PDIV), Partial Discharge Extinction Voltage (PDEV), and the maximum PD value (in picoCoulombs). The measurement results were analyzed using the Health Index method to classify the cable condition into good, warning, or poor categories. The results show that segment G3–G4 is in good condition, with PDIV and PDEV values above the nominal voltage and PD levels below the threshold. In contrast, segment G1–G2 was classified as poor, with PD levels exceeding 1.000 pC. Additionally, the quality of cable jointing was found to significantly affect the occurrence of PD. In conclusion, the OWTS method proves effective for non-destructive diagnosis of medium-voltage cable conditions and can support preventive maintenance of the power distribution system.
