不对称电流 meaning in English

asymmetric current

This paper introduces the three situations where the asymmetry of three - phase current takes place and proposes the calculation methods of the annexed line losses and of loss reduction when the addition of the three - phase current load is not equal to zero because of the asymmetry of the three phase load
