Abstract

This paper discusses a practical issue that arise when testing healthy and unhealthy cables by using Very Low Frequency (VLF). This issue is the Partial Discharge (PD). This study based on data from laboratory experiments and field testing. Partial discharge will be measured on 12/20 kV cables with power frequency, DC as well as with VLF. These cables are mainly used in medium voltage distribution network in Egypt. Cavities with different dimensions used as artificial defects to simulate the unhealthy case. The ability of using VLF to detect the partial discharge activities as an alternative for both of DC and AC of power frequency has been investigated.
