This article analyzes the ways to assess the additional power loss in the basic elements of power supply systems, arising from the asymmetry of the stress level. The article describes the relevance of reduction of electricity losses. Also described the negative effects while reducing the quality of electric energy. The necessity of taking into account the additional losses of energy from the electric current and voltage unbalance. Analyzed the main methods for determining losses in electrical equipment under asymmetric modes mains. The dependences of the additional power loss transformers TM series, the coefficient of voltage unbalance in the reverse order. It is shown that the values of additional power losses in the individual elements of the distribution network, in terms of an asymmetric mode, is needed to assess the total proportion of the above-mentioned losses in the total value of losses and determine the economic damage caused by a decrease in the quality of electric energy.
