Induction Method for Parameters Control of Cable Lines laying at the Electricity Distribution Network Polygon

This research paper investigates the specifics of the induction method in the tasks of controlling cable lines laying parameters. The goal of this paper is to look for opportunities to improve the induction method when solving the issues related to optimizing the cost of cable line excavation. For this purpose, we used line locator and research facilities at the university electricity research and training polygon at the middle voltage cable test and diagnostic laboratory. Such parameters for laying cable line in the ground as location and depth were determined during research, which made it possible to compare with the project documentation and identify minor deviations from the planned parameters. The signals of the line locator were tested in the places where the cable line is laid in the pipes and the possibility of finding their boundaries was revealed. Based on these results, the methodology has been developed that complements the existing induction method in pipe boundary detection tasks and makes it possible to identify locations for subsequent excavations. The obtained results are recommended to be used in the work of repair personnel on replacement and serviceability restoration of cable lines laid in pipes in the ground, and in the training process when developing professional competences of the personnel in electric power training areas.
