description: The subject of the graduate qualification work is "Development of solutions for protection against SPE in the distribution network of an industrial enterprise". This work is devoted to the study of single-phase earth faults and the development of methods to improve the operation of relay protection against SPE. Tasks that were solved during the study: 1. Design features of industrial enterprises. 2. Selection of the main equipment, which include transformers. 3. Calculation of short-circuit currents. 4. Study of the effect of intermittent short circuits on the network. 5. Analysis of the characteristics of the SPE transient process with different types of neutral grounding. The results of this work can be used in the design of power supply of production facilities. The principles of implementation and the composition of protection against SPE of 6-10 kV cable networks are analyzed. The main advantages of resistive neutral grounding and conditions for selecting parameters for relay protection are presented.
