Perhitungan Lama Waktu Pakai Transformator Jaringan Distribusi 20 Kv di APJ Yogyakarta

Distribution network owned by PT. PLN is a very important role to deliver electricity from generators to the load through transmission lines and distribution networks. Highly reliable network needed for the distribution of electrical energy can work continuously unbroken. Transformer is very important in the distribution network to distribute electricity from the main relay station to the load, so that the transformer can work continuously without any damage to the transformer needs to be elections that will be used, placement of the transformer at a large distribution network according to the load (kVA) is used, and regular maintenance in a certain period. In the calculations we use a transformer can predict when the use of transformers from the voltage and current calculations that are used every day, so if we tell the time using a transformer, we can prevent damage to the distribution network by replacing the transformer before the transformer damage.
