The work is devoted to the analysis of grounding devices of electrical installations in compliance with the normative technical documentation. It presents basic regulatory requirements for grounding devices and formulas for their calculation. The paper also presents the description of a developed application program using the integrated development environment for Microsoft Windows, Mac OS, iOS and Android Embarcadero Delphi, as well as the graphical interface and the components of the developed program. The functionality of the program offers a choice of the purpose of a grounding device, voltage value, input of the resistance of natural grounders and the ground fault current; providing the possibility of calculating the standards of resistance of the projected artificial grounder. A distinctive feature of the developed program is the ability of calculating the resistance of complex grounders from a horizontal grid and vertical electrodes used in 110 kV and above networks. A comparative analysis of similar software products is carried out, the advantages of the proposed analysis are indicated. In the longer term, it is planned to expand the features of the program, namely, to introduce the calculation of the resistance of complex grounders according to the well-known method [], the advantage of which is the calculation of grounders of complicated configuration using relatively simple calculation formulas.
