Abstract
"This scientific article examines the measurement method for determining the location of damage in a 6(10) kV cable line in a network with an isolated neutral. The method involves the use of location devices when measuring distances to the site of defecation in cable networks from two sides. This is necessary to identify complex types of short circuits and more accurately determine the distance to the accident site. The results of theoretical studies have been confirmed by experiments conducted using the R5–13/1 inhomogeneity meter together with the tracer measuring receiver–IP–8. In addition to the main experiments to determine the location of complex damage, experiments were conducted to study the parameters of the pulse measurement method. The influence of the instrumental characteristic of the shortening factor on the accuracy in determining the distance to the damage site is studied.. The method of two–way measurements of finding the distance to the place of damage in cable networks with a voltage of 6 (10) kV can be used to increase the continuity and reliability of power supply systems, as well as increase the level of electrical safety during their operation. Keywords: cable break, reflectometry, non–uniformity meter, electric grid, isolated neutral, grounding, damage location, simulation, isolation, reliability, power quality, emergency mode. "
