description: Topic of the final qualification work: "Designing protection against SPE in networks with different types of neutral grounding". This work is devoted to the study of single-phase earth faults and the development of a mathematical model of the enterprise's power supply network for the further development of methods for improving the operation of relay protection against SPE. Tasks that were solved in the course of the study: 1. Study of the effect of metallic and intermittent arc faults on the network. 2. The features of the flow of this process with different types of neutral grounding are analyzed. 3. Development of a Simulink model of a power system with an intermittent and stable arc fault to ground. On the basis of the "MatLAB" software package, a mathematical model of an intermittent short circuit was modeled. A number of oscillograms of intermittent arc faults to the ground were obtained for various types of neutral grounding.
