The load imbalance results in a current in the neutral conductor causing a large loss, so the resulting power loss is even greater. This causes the efficiency of the transformer to decrease. Decreased efficiency in this transformer can cause a decrease in the life of the transformer this will affect the performance in electric power to meet consumer needs. This study uses quantitative methods by collecting data by field observations to measure the load on the CR087P substation. From this study, it was found that the power loss value decreased after load balancing during the day was 7,081 kW to 4,917 kW, while at night it was 14,937 kW to 9,935 kW.From the results of the power loss, the efficiency value increases during the day after balancing from 98.03% to 98.63% and at night by 95.85% to 97.24%, it can be seen that the efficiency transformer is affected by power losses caused by neutral current.} }
