So to find out what the load imbalance is using the load balancing method of the transformer, we need to calculate the loading on each of the fastening and what the neutral current is inflicted. After that, you can analyze the load imbalance in each major on the transformer. In accordance with the calculation of the load imbalance condition of 19.43% and enter good category according to SPLN No. 017 year 2014 and the neutral current of 2,19%. And for the value of the loading transformer is 36.36%. In this case, the loading of the transformer is also still in katakana because it is still below 80% of its transformer capacity. After the analysis of balance of load in a department for A course of 33.33% in the department of B amounted to 43.3% at C. 26.43% and in D direction of 30.1%. So it can be seen that of the four majors are still in bad category because it exceeds the SPLN by25%.} }
