The transformer will experience a load which will affect the amount of life shrinkage and also the resulting efficiency. This study aims to analyze the magnitude of life shrinkage, analyze the effect of loading on life loss, analyze the magnitude of efficiency, and analyze the effect of loading that occurs on dry transformers at the Senayan MRT station and Bundaran HI MRT station. This study has several methods of analysis by calculating the load ratio, temperature hotspot on the transformer, life shrinkage for 24 hours to % relative age loss, and the life of the transformer so that it can find the results of the remaining life of the transformer. Percentage of loading for the Senayan MRT station is also smaller with the highest results reaching 18.44% and 19.96%, while the percentage of loading for the Bundaran HI MRT station has a higher yield with 32.49% and 34%, respectively. The result of age loss at MRT Senayan station is 0.069% with the remaining life of the transformer for 15.5465 years. The result of age loss at the Bundaran HI MRT station is 0.15% with a remaining life of 15.5425 years. The efficiency of the result at the Bundaran HI MRT Station with an average yield of 99,13%, while the efficiency at the Senayan MRT Station is 98,41%.} }
