Abstract

One of the effects of reduced transformer life is the frequent occurrence of disturbances, disturbances that can occur in the form of contamination of insulating oil which has an impact on transformer damage. To reduce the damage, a research was carried out, in this study it was carried out to see the effect of water contaminants contained in the insulation of transformer oil using the Breakdown Voltage method by looking at the value of the translucent voltage. There are 2 types of insulating oil used during testing, mineral, and vegetable oil, while the test equipment used is the BAUR Oil Tester DPA, with the standard IEC 60156:2018 test equipment. Which is adapted to the standard specification SPLN 49-1:1982 which states that new oil has a breakdown voltage value of 30 kV/2.5 mm. The results of the test show that the breakdown voltage value is influenced by water contaminants where the more contaminants contained, the faster the breakdown voltage value will decrease. This research can be an indication to maintain the transformer resistance.

Abstract

The problem in the tropics is the effect of temperature changes on the high voltage system, resulting in isolation around the electricity distribution in the 20 kV cubicle, which can trigger the insulation failure (breakdown voltages) on a feeder. To reduce the occurrence of power outages due to insulation failure with changing temperatures, direct testing is carried out by providing temperature variations ranging from 30oC to 90oC. To correctly understand the phenomenon, testing should be carried out. The test is carried out every 5 oC temperature increase. Based on the research results, a graph is obtained that explains the decrease in the breakdown value at 50oC, which causes the insulation breakdown voltage to be 27kV, and the decrease in the breakdown voltage at 90oC, which causes the insulation breakdown voltage to decrease to 22kV. Based on experiments, it can be concluded that the greater the temperature rise, The breakdown voltage appears more quickly. Thereafter, the data from the research results were tested using the linear regression analysis method, so that a MAPE obtained 3.89% and an RMSE obtained 1.33 were obtained with an average percentage obtained 0.37%.
