The article deals with the problem of reducing the loss of electrical energy when transmitting it over long distances in electrical networks. In particular, technical measures are considered that can compensate for the inequality in the capacity of overhead power lines. A mathematical model is presented that makes it possible to determine the parameters of the electromagnetic field of a power line taking into account its real design. Effective measures have been proposed for equalizing electric charges in phases. Specific recommendations are given for a 500 kV line with horizontal phases. Also, safety issues are considered, namely, the dependences of the electric field strength near power lines are obtained.
