1000 V distribution system and its potential in Russia

The application of the three voltage level 20/1/0.4 distribution system in Finland has proved to be an economic solution to enhance the reability of electricity distribution. By using 1 kV voltage level between medium and low voltage networks, the improvement in reability could be reached especially inaerial lines networks. Also considerable savings in investment and outage costscould be archieved compared to the traditional distribution system. This master's thesis is focused on the describing the situation in Russian distribution netwoks and consequent analyses the possibility of applying 1000V distribution system in Russia. The goal is to investigate on the basis of Finnish experience is any possible installation targets in Russia for the new system. Compatibility with Russian safety and quality standards are also studied in this thesis.
