However, the achievement of losses in October only reached 10.04%. So it is necessary to reduce losses so that the target of 8% can be achieved. One way to do this is to do load balancing. Balancing is done by exchanging the phases on the PHB-TR. Based on the calculation results, the imbalance at the RJLS substation: 33%, RJKS: 5% and MAI: 34%. After balancing it decreased to RJLS: 16% and MAI: 6%. The neutral current at the RJLS and MAI substations before balancing RJLS: 22.54A and MAI: 2.69A, after balancing it drops to RJLS: 9.54% and MAI: 11.53%. Losses caused by the transformer neutral current before balancing RJKS: 350.5 W and MAI: 3645.8 W, after balancing decreased to RJLS: 62.7 W and MAI: 91.7 W. Losses due to current flowing to the ground before balancing at the RJLS 1049.7 W and MAI 4651.2 W substation. After balancing, it drops to RJLS 538.2 W and MAI 1253.1 W. Energy losses in percent before balancing at the RJLS substation 8.3 % and MAI 26.78%. After balancing it decreased to 3.5% RJLS and 4.2% MAI. The conclusion obtained is that balancing the load using the phase swapping method on the PHB-TR can reduce the value of unbalance and neutral currents, so that losses can decrease.} }
