Abstract

In the first part of the bachelor thesis, the author examines the parameters of cable and outdoor lines. These properties are determined by used materials, diameter of conductors, choice of construction and placement of lines. The second part is about a single phase failures mostly about their formation and impact in operation of electricity network. The third part describes possibilities of compensating and location of the ground fault. In this part are analysed individual methods of location and compensate their principle, advantages and disadvantages. The last part is computational, which deals with the calculation of the earth fault current, the fault current of the single-phase short circuit.
