Determination of Network Impedance at the Place of Single-phase Load Connection

Original language description

As shown in the article, the asymmetry is directly proportional to the magnitude of single-phase power and indirectly proportional to three-phase short circuit power of system in the place of connection of load. In the article a ratio is derived betweenthe coefficient of the voltage asymmetry u, the single-phase load S1f and the three-phase short circuit power with improvement of Fortescue´s theory of symmetrical sequence components. With use of this relation is shown an idea to investigate the short circuit power from measured values of the coefficient of the voltage asymmetry u and single-phase load S1f.The results of verification measuring which was realised in a traction transformer substation of electric railways 25 kV; 50 Hz of the Czech railways are mentioned in the article too.
