Abstract
Due to the increasing importance of high voltage DC components in the transmission systems, HVDC-specific diagnostic methods will become indispensable. In AC systems it is possible to perform a partial discharge diagnostic analysis about the nature of the fault based on the way and the phase angle in which partial discharges occur. Unfortunately, a similar technique is, due to the lack of angular references and time invariability in the case of HVDC systems, impossible. Based on these considerations a method based on a wavelet packet decomposition for the classification of partial discharges is presented in this contribution. Partial discharges were induced and measured in models of typical faults in solid insulation systems in two different polymeric solid insulation materials. Special test sequences optimized to reduce the influence of space charges and to analyse the influence of the voltage and the test period as well as the type of used measurement bandwidth were implemented. The use of the investigated method shows a good performance in classifying partial discharge sources, which demonstrates the potential of wavelet packet decomposition for the development of diagnostic tools.
