Loading a transformer that exceeds 80% of its rated capacity can shorten the life of the transformer itself. Moreover, the large number of subscribers supplied resulted in an overloaded transformer. The transformer at the JPR 021 Distribution substation has a loading capacity of 56% during the day. This situation is still ideal because the transformer loading is still below 80%, the percentage of loading at night transformer JPR 021 has a loading of 84%. With this load, if the load sharing is carried out from Transformer JPR 021 to the surrounding transformer, namely transformers JPR 131 and JPR 054 will cause the two transformers to overload and for the relocation of the transformer cannot be d thus load sharing and relocation to the nearest transformer are deemed ineffective. This situation causes the transformer load to be declared overloaded because the load on the transformer has exceeded 80% of its maximum capacity.one because the capacity of the transformers in the vicinity has the same power. With the addition of the insertion substation, it is expected that the percentage of overload load experienced by the JPR 021 distribution substation can return to normalor even less than 80%.} }
