5. CONCLUSIONS AND RECOMMENDATIONS 5.1 Conclusion 1. It has been made real time analysis system losses due to load imbalance in labview-based transformer in order to facilitate the giving of information loss suffered by visualization informative accurate and can be easily applied. 2. Evaluate the results of the analysis on load balanced total losses 191.14 Watt, the efficiency of 55.06%, which appears neutral current 0.0392 A, 14.16% K factor imbalance, unbalanced load models A total losses 186.24 watts, efficiency of 54.36%, which appears neutral current 0.1986 A, 46.36% K factor imbalance, unbalanced load Watt model B 192.77 53.89% efficiency that appear neutral current 0.2202 A, factor imbalance K 49 , 76%. So that the unbalanced load transformer leads to efficiency losses are getting smaller and the neutral current increases. 5.2 Recomendations 1. Further research can be done by varying the load with a variety of resistive, inductive and capacitive made disproportionately. 2. Development of the system can be done by using an interface that has more IO channels, making it faster and easier to perform the measurement. 3. The system can be expanded with the use is as a data logger that allows you to record losses each time as needed. BIBLIOGRAPHY 1. Kadir, Abdul. 2000.
