Abstract

Partial discharge (PD) measurement is an established condition monitoring technique used to assess the deterioration of high voltage insulation systems such as power transformers and gas-insulated switchgear. Two popular monitoring techniques employ radiated RF measurements and conventional apparent charge measurements according to the IEC60270 Standard. Recent research has shown that combining simultaneous radiated RF with IEC60270 measurements of PD events appears to provide additional information to assist in the discrimination of specific insulation faults. This paper aims to show for sample voids in resin that the frequency content of the radiated RF signals can be used as an additional discriminatory feature for simultaneous RF and IEC60270 measurements in identifying PD produced by single and multiple resin voids under electrical stress.
