Abstract

In an effort to provide reliable and efficient electrical energy, substations have an important role in regulating the demand for electric power loads and as a center for securing electrical power system components in a certain area. Frequent disturbances become a benchmark for an electric power system whether or not it is good or not in an effort to provide reliable and efficient energy. One of the maintenance measures is temperature measurement using thermal imagers, which is commonly referred to as thermovision measurement.Thermal imager is a tool that can be used for predictive maintenance activities to monitor the condition and performance of an equipment so that the possibility of equipment failure can be minimized. In October 2020, after thermovisiting transformer bay 6 at the Sunyaragi substation, it was discovered that there was a hotspot on the T-phase separation blade, causing heating of the blade, the above conditions can result in a decrease in PMS performance, with the worst condition if left alone can result in damage to the PMS blade and can also melt when the peak load is on the transformer 6. Under these conditions, maintenance is carried out by maintaining contact resistance, insulation resistance, and grounding resistance. The results of the analysis of contact resistance after maintenance show that the equipment is in good condition and still suitable for use, with a value of 7μΩ for the R phase, 6.5μΩ for the S phase, and 6.7μΩ for the T phase.

Abstract

Electrical energy is an important factor to support people's lives. Electrical energy from the generator is channeled through a transmission line to the substation. Transformer (transformer) is a very important equipment in the electric power system. Inside there is oil which functions as an insulating medium and also as a cooling medium. This electrical and thermal load can cause dissolved gases in the transformer oil. This DGA (Dissolved Gas Analysis) test aims to determine the content of dissolved gases in transformer oil and then to analyze using three fault indication methods Total Dissolved Combustible Gas (TDCG) Method, Roger Ratio, and Duval Triangle. Results The analysis uses these three methods to determine corrective actions according to the condition of the transformer oil. Corrective action to return the dissolved gases in the transformer oil back to normal. Transformer oil filtering aims to remove or reduce potentially damaging gases from the transformer oil content. On December 29, 2020 the transformer experienced an increase in the content of flammable hydrogen gas and acetylene gas, the TDCG value was 1520 ppm and after corrective action the dissolved gas content decreased to 481 ppm, so that the condition of the transformer oil returned to normal.
