In our dynamically growing word the power energy and qualitative, continuous electricity-supply has a crucial role. With a well designed grounding system the reliability of the electrical equipments can be improved. The thesis is divided into two main sections.
In the first part I present the terminology based on the literature and the standards, I bring forward the substations earthing systems, and I exemplify the measure method of the resistance to earth and the touch- and step voltage. Furthermore I present the limit values according to the Hungarian standard in use. In short I present the used Canadian CDEGS software package.
In the second part I introduce the tested simulations via the CDGEGS application. I present the examinated network. During the simulations I have investigated substations ground potential rise, the touch- and step voltage and the transfer potential. After the simulations I collated the results with the allowed limit values.
