Leakage impact on load flow calculation of electricity network. The article is about the load flow calculation of electricity network at two branches of transmission system. There are several modelled transfers of real flows in order to find the amount of losses caused by modelling of leakage conductibility. For this reason there were chosen lines of 220 kV V207 (Sokolnice - Tábor) and 400 kV V413 (Prosenice - Řeporyje). Calculations of losses were done on models of lines with leakage conductibility and without it. On the base of calculated loses difference there is made an evaluation how the leakage influences amount of loses at EHT line.
