Abstract

Very low frequency (VLF) method may be used for analysis of changes in the power cables´ dielectric and electrical parameters during the service lifetime. This paper focuses on a more detailed description of this method and VLF method usage in the laboratory measurement conditions of the power cables. In the second part of the paper we specifically focus on this method applied for measuring the dielectric properties of the cable type 6-AYKCY 3×240. The aim was to analyze changes in dissipation factor values of power cables exposed to thermal aging during 135 days period.
