The review and analysis the destructive effects of harmonics on a sample MV/LV transformer

Considering the effects of non-liner loads to create harmonics and replacing these loads instead of household, commercial and industrial customers, create many voltage disturbances every year. Harmonics will cause specific problems in the power distribution networks. Some of these problems could be unsuitable function of equipments from these networks, decreasing their lifetime and their efficiency. Therefore, we need to study harmonics and show the way to resolve these problems.
