Abstract :
Power transformator is one of the most important equipment and valuable in the process to distribute electrical energy. It is expected that a power transformers can have long lifetime, less shrinkage of the lifespan and the efficiency high. One of the factors that can affect it is the loading demand. This study uses quantitative methods. From the results of data processing referring to IEC 354, SPLN 17A and IEEE C57.91 2011, it was found that the shrinkage value of transformer age 4 Duri Kosambi substation is still very low that is 0.00204% with a efficiency value of 99.8%. This is because the resulting hostpot temperature is still below standard (110 ) which is 97.41 . But if there is load growth and increase the hotspot temperature up to 110 , there will be an increase in the shrinkage value of the age and a decrease in the value of the drastic efficiency
