Abstract :
Customer growth continues to increase every year at PT. PLN (Persero) UP3 Depok, especially in the Protocol Feeder, can certainly trigger an overload, so that it can cause the current to flow and the power generated to increase which causes heat and damage to the insulation. Efforts were made to overcome the occurrence of transformer overload events including load distribution (load transfer) which was carried out by moving the load at the AGN Substation to the PIS Substation which previously experienced a state of under-load. The researcher conducted an analysis of the transformer loading on each conductor before and after the load breaking activity was carried out. The parameters used in the loading analysis are the percentage of the main conductor loading, the percentage of loading between phases, and the percentage of imbalance in each transformer. The hypothesis in this study that load rupture and load equalization can reduce the overload on the transformer. Prior to load rupture, the AGN transformer measured at Full Load Time (WBP) had a loading percentage of 81.4%. Then, the load is broken outside the Full Load Time (WBP) with reference to the measurement results at the Full Load Time (WBP). The load measurement was again carried out after the load rupture process was completed with the loadx calculation results reaching 57.5%. The load breaking method that has been done can reduce the load by 23.9%.
