Jednopólové a třípólové poruchy v distribučních sítích.

Abstract

This bachelor thesis summarizes information on single- and three-pole failures in distribution networks. In the first part of the thesis, the author deals with the description of cable and outdoor networks low voltage and high voltage and their parameters. In the second part of the thesis, he discusses the analysis and description of what are the causes of single-phase short-circuit and three- phase short-circuit and also its processes. The third part discusses various possibilities of compensation of earth capacitive currents. The subsequent fourth part is possibilities of locating the place of the earth connection and its appropriate methods. In the last fifth part, an example of the calculation of the three-phase short circuit and the natural connection in the model network is processed.
