The article analyzes the well-known methods for calculating electricity losses during the transmission of electricity in the elements of the electrical network. The problem of the need to take into account additional losses of electricity in non-sinusoidal and asymmetric modes of operation of rural electrical networks with a voltage of 0.38-10 kV is formulated. The authors propose to take into account additional power losses under the conditions of simultaneous impact on power losses of many factors, such as: power factor, current asymmetry level, current non-sinusoidality level in the linear wires of the network, ambient air temperature, service life of the network element.
