		abstract={Distribution transformers are important equipment in the distribution of electrical energy in electric power distribution systems, therefore, distribution transformers are attempted to be used in accordance with the estimated life of the transformer from the manufacturer. When the transformer is charged stable at its rated temperature with a temperature of around 20 ?, the transformer hotspot temperature will reach 98 ? and can be in accordance with the normal age shrinkage. In this study the transformer which was overloaded with value had a large shrinkage of 436.83% at the DK259C substation and 285.6% at the MK57AS substation. While the transformer with normal loading has a normal shrinkage value of 86.6% at the DK47C substation and 71% at the KDR227 substation. The higher the loading will increase the temperature of the transformer, this heat increases the insulation on the coil to be worn so that it can also shorten the life of the transformer therefore increasing this temperature must be maintained and high loads need to be sought to increase so that the transformer remains stable and reduce age shrinkage in the transformer.}
