Analysis of estimated age of distribution transformer against loading at ULP Panakkukang with the montsinger method

Abstract

Distribution transformers are electric power equipment that plays a role in distributing electricity to consumers from medium voltage to low voltage through transmission lines. Factors affecting the life of the transformer are overloading and ambient temperature are the main factors affecting the life of the transformer. This study aims to analyze the increase in transformer load, the age losses that occur in the transformer, and the age of the transformer. The time series method is used to calculate the load forecast that occurs each year, and the Montsinger Method is used to obtain the relative speed values of the transformer. In this study, the data used were ten types of transformers at ULP Panakukang. The results are in the form of a yearly increase with different increases. Calculation of the remaining service life of the transformer obtained from each substation is 13 years for GT PHB016, six years for GT PHB021, two years for GT PHB031, 14 years for GT PHB 095, 18 years for GT PKS073, seven years for GT PKS075, six years for GT PTP024, nine years for GT PTP034, 16 years for GT PRC024 and six years for GT PBG002.
