Medium Voltage Cable Testing Equipment

Today we overview chapter 14.

Medium voltage cable testing equipment. In the absence of manufacturer s published data use table 100 1. Type testing of medium voltage cable accessories. Perform an insulation resistance test individually on each conductor with all other conductors and shields grounded. In this series of 15 blogs we provide chapter breakdowns for the nexans published book medium voltage cable accessories a theoretical and practical approach.

This unique system with its truly sinusoidal voltage shape no distortion allows non destructive vlf testing and condition evaluation of high voltage cables in compliance with vde iec. Making them useful especially for field testing where transport and space can be issues. Vlf cable testing very low frequency is a technique for testing of medium and high voltage mv and hv cables. Type testing of medium voltage cable accessories by chris dodds on 1st november 2013 follow thorneanderrick.

Apply voltage in accordance with manufacturer s published data. Baur s truesinus is a voltage generation technology invented in 1990 and patented in 1995 for the very low frequency vlf high voltage cable test equipment. Ac hi potential testing this method uses ac high voltage for the testing of cables and other types of electrical equipment at a level greater than the rated voltage of the tested equipment. Vlf systems are advantageous in that they can be manufactured to be small and lightweight.
