Abstract :
The use of electrical energy simultaneously at a certain time can result in an increase in the load and electrical power of a distribution transformer. Load unbalance in an electric power distribution system will always occur. This happens because of the presence of a neutral current that appears on the neutral delivery so that the load is indicated to be unbalanced. In analyzing the problem using a mathematical model calculation which includes the transformer loading equation, transformer load imbalance and losses (losses). After analyzing the data, it shows that the load imbalance that occurs is high and the neutral current that appears is also large. The DC142 transformer has the highest load imbalance value on Saturday, March 7, 2020 at 35.56% (Noon) and 58.2% (Night). The highest losses occurred on Sunday, March 08, 2020 during the day worth 0.926 KW while at night it was worth 2,463 KW. Based on this, the greater the value of neutral current, the greater the value of losses.
