This paper will review the propagation characteristics of radio frequency emissions in metal-clad medium voltage switchgear. The radio frequency emissions will be generated using various sources of partial discharge and measured using a prototype distributed antenna based partial discharge detection system. It will be shown that partial discharge sources of varying type and magnitude can be detected...
Recently, non-contact radio-frequency (RF) methods have shown promising potential to be used as a complement to the IEC 60270 standard method for the detection and localization of partial discharge (PD) in high voltage insulation. This paper reports the results of an experimental investigation on the characteristic of partial discharge in an air gap using the (RF) method combined with the high-frequency...
