- In this paper, a method for power losses evaluation in single phase transformers is presented. This research focuses on the transformer losses under nonlinear loads with a sinusoidal supply voltage. A practical approach is proposed which allows for the observation of harmonics. The total harmonic distortion and losses were analyzed and shown. Moreover, the relationship between transformer losses and harmonics are reported. The Experimental results show that the proposed method can determine the effects of harmonic components on transformer losses.
