Аналіз основних методів контролю стану кабельних ліній електропередавання в розподільних електричних мережах

Abstract

The abstracts consider the current problems of ensuring the reliability of power cable lines in distribution electrical networks. The main factors affecting the condition of cable insulation are analyzed, and attention is focused on the main types of damage that occur during operation. Special attention is paid to the need to implement technical diagnostics systems and non-destructive testing methods that allow for timely detection of defects, assessment of the residual resource and continuous monitoring of the condition of the insulation. The advantages of new approaches to testing that do not affect the network operating mode are also emphasized. The conclusions substantiate the relevance of further research in the direction of improving the methods of diagnostics and prediction of the reliability of cable lines.
