Title: Practical Issues Regarding the Use of Dielectric Measurements to Diagnose the Service Health of MV Cables
Author: Hampton, Nigel ; Hartlein, Rick ; Hernandez, Jean ; Harley, Ronald
Abstract: During the last decade, Very Low Frequency (VLF) testing for extruded distribution cables has gained interest among the North American utilities. The increasing interest is evidenced by recent research publications and discussions inside the expert community in which standards are being proposed and continuously discussed. While there is a general consensus as to the meaning of insulation dielectric properties, many open issues still remain for discussion in order to produce a more accurate evaluation. Consequently, this paper will discuss a number of the practical issues that arise when making these measurements at VLF on field aged and non-aged cables, particularly Tan δ measurements. The discussion is based on data from laboratory experiments and field testing.
