Partial discharge (PD) detection is an effective method for finding insulation defects in HV and EHV power cables. PD apparent charge is typically expressed in picocoulombs (pC) when the calibration procedure defined in IEC 60270 is applied during off-line tests. During on-line PD detection, measured signals are usually denoted in mV or dB without transforming the measured signal into a charge quantity...
The attenuation characteristics of a partial discharge (PD) pulse propagating in a long-distance power cable is always a concern for PD detection. The high frequency attenuation of the symmetric PD pulse waveform has been previously well modeled, and the approximate solution concerning the asymmetric pulse has also been discussed. In this paper, a method to calculate the attenuation characteristics...
