The major nonlinear effects in transformer core are saturation, eddy current and hysteresis. Saturation is the predominant effect in power transformers, followed by eddy current and hysteresis effects. In saturation, a transformer core act as a source of current generating harmonics, some of which will flow directly toward the primary and secondary windings. The method is based on harmonic content evaluated of the transformer no-load current with high magnetic flux density subjected. The investigation is done on single phase model core type transformer. The transformer is connected to variable voltage variable frequency (VVVF) source and the investigation is done on the same flux density. The result has been compared with normal frequency supply (50 Hz).The results show that the harmonic content increase significantly when high magnetic flux densities are injected. 2010-11-30T04:13:18Z 2010-11-30T04:13:18Z 2010-06-23 Working Paper p.382-385 978-1-4244-7127-0 http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5559192 http://hdl.handle.net/123456789/10348 en Proceedings of the 4th International Power Engineering and Optimization Conference (PEOCO) 2010 Institute of Electrical and Electronics Engineers (IEEE)
