Study Of The Effect Of Load Balance In 500 kVA Distribution Transformers In Complex Pt. Perta Arun Gas Area Of 17 Dumai Branch Lhokseumawe City

摘要

For optimal distribution of electricity to the industry requires transformers as the heart of transmission and distribution. Therefore, the transformer is expected to optimize optimally. Given the hard work of the transformer and to maintain the durability of the equipment, the transformer load cannot exceed the capacity and there is no large load. The supply of electricity that is stable and continuous is a requirement that must be used in electricity needs. In meeting these needs, there is a division of loads that are initially the same because when the same time each which then causes an imbalance that damages the supply of electricity. Load imbalances are things that cause technical losses. In order to achieve a stable supply of electricity and continuity to consumers, it must be overcome. This study aims to determine the magnitude of the load imbalance on the distribution transformer and to determine the losses (losses) caused by the load imbalance in the distribution transformer. The method used is by taking data technically, measuring on secondary side transformers, calculations based on measurement data. The results showed that the percentage of load imbalance in accordance with the calculations during the day was 13% and on the same day 7.6% and the difficulty of losses due to the current flowing on the transformer neutral conveyor based on the daytime calculation of 0.17% or 0,79 kW and at night 0.23% or 1,075 kW.
