Where in the distribution of electrical energy required a considerable distance from the substation (GI) To arrive at the consumer or customer, so there is a significant voltage regulation. Therefore we need the arrangement of the secondary distribution system by improving the voltage drop by adding a Distribution Transformer, so that the performance of the transformer works better. So I will discuss about Repairing Drop Voltage by adding distribution transformers in the Bamboo Region. Against voltage drops and power losses at the distribution substation at PT. PLN (Persero) UP3 Kebon Jeruk Jakarta, So that the acquisition of the tip voltage at the voltage drop for the Department of A ?Vr is 11.45%, ?Vs is 11.90%, and ?Vt is 12.5%; Department B ?Vr is 11.90%, ?Vs is 12.31%, and ?Vt is 11.6%. For calculations after the addition of the new Kj416 substation to the voltage drop in Department A, it is obtained ?Vr by 10%, ?Vs by 8.9%, ?Vt 9.8%; While Department B ?Vr was 6.68%, ?Vs was 7.81%, ?Vt was 7.36%. Voltage at Kj314 substation before adding a new substation from the acquisition of voltage drop, while at the addition of the new Kj416 substation the results of the voltage obtained are normal. Power losses at KJ314 substation before the addition of substations at 94.6 Kw; Power losses at the old substation After Addition of KJ314 Substation 0.80kW; The power losses at the KJ416 substation are 0.825 kW.} }
