		abstract={The power transformer is an important and most expensive equipment in the process of distributing electric power, therefore it is expected that a power transformer can have a long service life, small life loss and high efficiency value. One aspect that can affect this is the pattern of loading, this study also uses quantitative methods. From the results of data
processing that refers to IEC 345, SPLN 17A and IEEE C57.91 2011 it is found that the value of the life loss of the transformer 5 at the kosambi substation is still low, namely 0,000544%
with an efficiency value of 99,8% This is because the resulting hostpot temperature is still below the standard (110°c) is 86,39 °c but if there is a load growth that causes an increase in
the hostpot temperature until it reaches(110 °c ), there will be an increase in the value of shrinkage age and a significant decrease in the value of efficiency. Based on research and
calculations, it can be seen that a drastic increase will occur in 2024 with the hotspot temperature reaching 110.3 °c with an age loss value 0.0453% and an efficiency value of 95.5%.}
