On overhead networks transfer from 10(6) kV to 20 kV

The expediency of preferential use of the rated voltage of 20 kV for the overhead networks of Russia is investigated. The feasibility study of the 20 kV voltage application areas based on the integrated parameters of the networks was performed. It is shown that due to the convergence of technical and economic characteristics of 10 and 20 kV equipment, 20 kV networks have more significant advantages in comparison with traditional 10 kV electrical installations.
