Improving the efficiency of technical means and methods for diagnostics of isolation of high-voltage distribution networks

Abstract

This work is aimed at developing and improving diagnostic equipment used in high-voltage distribution networks by modeling electromagnetic transients and expanding the functional part of devices. Presented are models of a three - phase distribution network and a high-voltage part of a test installation forming a technological system "diagnostic device-distribution network". Examples are shown of wave processes in the simulated system during insulation breakdowns, load characteristics of the test installation during operation of the device are shown, which makes it possible to optimize insulation control methods and technical diagnostic tools for electrical laboratories. Disclosed are examples of calculating the location of damage in case of insulation failures in different sections of the controlled network based on the analysis of wave processes in the line.
