Losses on the transformator cause excessive transformer loading so the transformer must be increased in capacity to meet the customers?s electricity needs through increasing the transformer capacity. Losses the natural current before upgrading during the daytime P_N=0,538 kW and I_N=232 A also at night P_N=0,153 kW and I_N=126 A, and after upgrading the natural current during the day time is P_N=0,510 kW and I_N=226 A also at night P_N=0,144 kW and I_N=120 A. So to make a stable and continues to consumen so, This was overcome by Uprating the 400 kVA Transformer.} }
