Abstract
From analisys of data, value of efficiency percentage and losses that generated in transformer 54 MVA at PT. PLN (Persero) Keramasan Power Plant. To know value of efficiency and losses of transformer 54 MVA PLN Keramasan got from manual calculation. The calculation by manual is did with collect the data like input power and current of load used in transformer. In manual calculation, output power in highest load is 33715 KW, in average load is 50.831 and in smallest load is 38.843. The smallest total losses when the smallest load is 156,861 KW and the biggest losses total when the biggest load is 134,827 KW. The biggest efficiency in transformer PLN Keramasan is got from when the smallest load is 99,59 %, and the smallest efficiency is got the biggest load is 99,6 %. Efficiency and losses is very affected by power and current of load used. The bigger power and current so the bigger losses of transformer and the smaller efficiency of transformer.
