STUDI PENGARUH PENUAAN (AGING) TERHADAP LAJU DEGRADASI KUALITAS MINYAK ISOLASI TRANSFORMATOR TENAGA

Abstract

The lifetime of transformers and equipments are highly dependent on the quality of insulation system. Insulation is one important component in a transformer because generally, insulations used liquid and solid insulation in accordance with its function as an insulating material and cooling media. At the time there used transformer oil aging and damage caused by several things such as impurities, water content, dissolved gases (Dissolved Gas Analysis-DGA), acidity and heating the oil. Transformers loading will cause a decrease in the quality of the transformers insulation system that resulted in the decreasing age of insulating oil. This Final Project explained the influence of loading on the rate of decline in quality (degradation) of power transformers insulating oil. This research was conducted using sample data loading and maintenance of transformers by obtained directly with investigations into the transformers which is operating. By using samples from a variety of loading conditions of the transformers with different levels we can see the quality and worthiness of insulation oil and the estimated the effective remaining life of transformers insulation system.
