Streszczenie:
The paper considers the real technical possibilities of improving the protection of power lines in their operation. The study is based on a methodology that combines a systematic analysis of the principles of functioning of power grids of energy-intensive enterprises with an analytical study of the main aspects of protection of 10 kV lines and access roads from overvoltages. The results of the work are important for developers and designers of power grids of energy-intensive enterprises, as well as for specialists involved in the maintenance of power grids that include lines and access roads with specified operating voltage parameters.
