Abstract :
Technological advances and the very important role of electric power to meet customer needs, requires the State Electricity Company (PLN) to always try to improve the quality and reliability of the distribution of electrical energy to customers as outlined in the form of road map to reduce transformer disturbances from year to year to get a company with service world class. Transformers are electrical equipment that is very important because it deals directly with the electricity transmission and distribution channels. Interference with the transformer can cause damage and decrease the performance of the transformer. Examples of causes of transformer damage are overload and unbalanced load. Overload occurs because the load attached to the transformer exceeds the maximum capacity of the transformer where the load current exceeds the nominal load current on the transformer. Therefore, it is necessary to improve efforts by reducing the number of transformers overload which is one of the improvement initiatives obtained by carrying out the work of breaking the load. After the breakdown of the load, the phase load and the total transformer load decreased in each phase from 995.004 VA to 620.216 VA and the total percentage of the transformer decreased from 99.5% to 62.02% so that the transformer was normal and could work optimally.
