Abstract :
Generally, the load served by a transformer in the distribution system will be endeavored to remain in a balanced condition, but in fact load imbalances still often occur. The appointment of this title is to determine the magnitude of the influence of load imbalances that often occur in distribution transformer at Komp. B.P.G UNP substation on the reliability of the transformer. This study uses the observation method to obtain fault data and transformer load data. In this study, the calculation of the transformer imbalance at the Komp substation was carried out. B.P.G UNP fresh water feeder and found the load imbalance in February was 28.3%, in March it was 30.6%, and in April it was 45.6%. To determine the reliability value of the transformer, the Weibull distribution method is used and after the calculations have been carried out on the transformer, is obtained the average failure rate is 6.15077% per year which affects the reliability value of the transformer. The value of the reliability of the transformer was obtained at 0.349676 and based on the level of reliability of Cronbach's Alpha this transformer can be said to be quite reliable.
