Abstract :
Losses are the loss of the amount of energy that is generated, which affects the amount of energy that can be sold to consumers and affects the level of profitability of the company. The size of the losses from an electric power system shows the level of efficiency of the system. The research method in this thesis uses quantitative methods. In a feeder there is a transformer which has overloaded and is transferred to a larger capacity, then the losses from the transformer are calculated. One of these problems occurred in the KJ139 substation with a capacity of 400 kVA where overloaded transformer loading was 93.00% and SP79S substation with a capacity of 630 kVA with a low load of 17.74%. After the mutation of the percentage transformer loading on the KJ139 substation became 59.04% and in the SP79S substation became 39,98%. In addition, transformer losses fell by a difference 2374,461898 kWh/year. By performing transformer transformations, available transformers can be used optimally to overcome the low transformer loading and overloaded transformers even though the transformer supply is limited.
