Abstract

The existence of triplen harmonics in equipment has been recognized dated back in the 19thcentury. Even though many discovery has been made regarding the behavior of triplen harmonics in electrical equipment, many scope still needed to be studied and researched. Thus, the objective of this paper focuses on the characteristics of triplen harmonics produced by synchronous generator flowing through various transformer winding configurations subjected to several of load conditions. The scope of experiment for this study covers on the laboratory experiments using lab-scaled salient pole synchronous generator that connects directly to the transformer and load. The transformer has four winding configurations and the load can vary in different resistance and inductance connections in a circuit. Since the third harmonic voltage produced by generator are in phase or zero sequence in nature, the third harmonic current depend on transformer winding configuration, the load impedance magnitude and phase angle. In conclusion, this study provides a very important knowledge regarding the third harmonic flowing through transformer. Different kinds of transformer winding configuration have their own characteristic. Third harmonic voltage and current magnitude alone may not give correct indication to their severity because they are vector quantity and rely on zero sequence network, load impedance magnitude and phase angle.
