摘要：Harmonics in current has become an apparent and important consideration in designing a power transformer. This is due to the fact that the loads now have become nonlinear in character. These new generations of loads are invented to assist various functions in homes, factories, offices, and factories. However they created distortions at the current shape thus causing terrible consequences toward power transformers. Most of transformers are designed, manufactured, and calibrated using only sinusoidal shape current. Thus the existence of harmonics clearly upset the operation parameters such as the increased losses the transformer experienced. This paper tends to look into designing a power transformer that considers harmonics in current. Steps in designing a particular transformer are shown to emphasis the areas needed to be change whenever the current consist harmonics. An initial design is made with only sinusoidal current while the second design would consider harmonic components in current, up until the 11th order. Some recommendations on enlarging size of the core dimension is made at the end of the paper.
