Abstract

A 20 kV cubicle is a set of electrical equipment installed in a distribution substation as a distributor, circuit breaker, connector, controller, and protection system for the 20 kV voltage power distribution. The frequent issue in these cubicles is corona discharge on electrical equipment, which is a phenomenon occurring when the air around conductors or conductive materials becomes ionized, resulting in the release of charges that can lead to insulation failure in the equipment. The consequences are severe as it can damage the equipment inside the cubicle and cause power losses. This research analyzes the influence of humidity, temperature, sound, and light conditions inside the cubicle to identify the symptoms of corona discharge in the 20 kV cubicle and its accessories. The goal is to create a tool that can address and anticipate the issues related to corona discharge caused by the effects of humidity, temperature, sound, and light.

Abstract

An overhaul is a process of dismantling a problematic engine so that it can be examined more thoroughly. During the overhaul, the problematic engine components are replaced. The overhaul of the sphere gap setting of the semi-automatic high impulse voltage generation is also intended to maximize the K3 system and the level of accuracy when conducting research on impulse voltage generation. The current condition after the occurrence of damage to the automatic sphere gap adjustment machine. The sphere gap setting is done manually, causing the desired ball gap distance to be not very accurate, and the risk of work accidents is higher in the high voltage laboratory. In the first stage of work, an inspection and measurement were carried out to replace the capacitor and limit switch components because they could no longer be used. As well as improvements to the electromagnetic brake components. From the test results, it was found that the distance measurement was as expected and it can be proven that after an overhaul, the semi-automatic spacer can function normally again so it can make it easier to conduct high voltage impulse research. In addition, from a security point of view, it is better because the spacing between the balls is done outside the high-voltage impulse generation cage

Abstract

This study aims to analyze the comparison of breakdown voltage between purified and non-purified transformer oil in the Unit 1 transformer at PLTA Malea. The research focuses on evaluating the quality of transformer oil as an insulating and cooling medium to maintain transformer performance and reliability. The research method used was an experimental method by conducting breakdown voltage (BDV) tests on transformer oil samples before and after the purification process. The testing was carried out using an Insulating Oil Tester in accordance with the IEC 60422-2013 standard, with an electrode gap of 2.5 mm, and each sample was tested six times to obtain the average breakdown voltage value. In addition, supporting tests including viscosity and moisture content measurements were conducted to evaluate the changes in the physical characteristics of the transformer oil. The results showed that the non-purified transformer oil had an average breakdown voltage of 55.11 kV, which was considered unsuitable for operation because it was below the minimum standard. After the purification process, the average breakdown voltage increased significantly to 77.95 kV and met the operational requirements based on the IEC 60422-2013 international standard. These results indicate that transformer oil purification is effective in improving dielectric strength and insulation quality, and therefore can be recommended as a preventive and corrective maintenance method to maintain transformer reliability and extend its operational lifespan.
