Abstract

Partial discharge (PD) is a phenomenon of releasing an electrical charge in insulation materials of high-voltage equipments, and if it happens continuously, it will result in a breakdown of the insulation material damaging the equipment. PD produces electromagnetic wave radiation that should be and can be detected with an antenna. Based on the above conditions, this research will discuss multi-source partial discharge (MSPD) detection using loop antennas in oil isolation. The MSPD is modeled with two electrodes that are sphere-plane and sharp-plane electrodes in two chambers. The distance of electrodes is varied of 0.5 cm and 1 cm. The distance of the antenna is also varied of 15 cm, 20 cm and 30 cm. The oil we used was Shell Diala B oil. The signal captured by the Antenna will be compared with the leakage current detected High-Frequency Current Tranformator (HFCT) in order to ensure that the loop antenna detects the electromagnetic emission properly. The Phase Resolved Partial Discharge (PRPD) was also analyzed as the signature of PD. Tests carried out in pre-breakdown conditions. The results showed that the antenna could detect MSPD in oil isolation with evidence of comparing the HFCT signal, and the Antenna has the same characteristic when PD occurs. PRPD MSPD data on the Antenna has a pattern like a tapered triangle. At 0.5 cm electrode distance, PD often appears at a phase angle of 122. 4°;151.2° and 320. 4°, while the electrode distance of 1 cm tends to appear at the same phase angle, which is 320. 4°. This PRPD was consistent with the results of several studies done before. The farther the electrode distance, the greater the magnitude of PD. Regarding the antenna distance variation, generally, the closer the antenna distance to the PD source, the better at detecting PD.
