Partial discharges (PD) have been successfully recorded measuring both the simultaneous RF radiated energy and the apparent charge according to the IEC60270 Standard From the measurements, correlation graphs are plotted The correlation graphs provide an insight into the dynamics of the related current pulses associated with the discharge geometry. This paper makes attempts to quantify mathematically the RF energy and apparent charge correlation curves and clusters arising from specifically made resin void samples. A comparative analysis of multiple void samples with free particle in oil samples prove that the correlation depends on a number of factors such as the number of voids and the influence of multiple radiating sources.
