PLN (PERSERO) AREA CENGKARENG}, year={2019}, url={http://156.67.221.169/519/}, abstract={Electricity has long been an important need in many ways, including in modern times. Even electrical energy has become a daily basic need to support a variety of activities. Distribution transformer is one of the important components to channel electrical energy to be used by consumers. In the distribution of electrical energy distribution transformers have a significant role to distribute electrical energy directly to consumers and even have very close position to consumers. But in the implementation it does not mean that there are no obstacles in the operation. As time goes on, the distribution transformer's age decreases. Depreciation of age is the effect of loading on distribution transformers. For the smooth distribution of electrical energy in the Cengkareng Area, the age of the distribution transformer must be one of the things that is considered by the PLN Cengkareng Area.} }
