Time and frequency domain analysis of partial discharges using electrical method

Partial discharge (PD) measurement results with particular consideration of time domain and frequency domain analysis of pulses generated by PD model sources are presented in the paper. Three different PD generation model sources are selected for the research: surface type, point to point and multi-point to plate. All measurements are proceeded under laboratory conditions using electrical method of a PD detection, according to the IEC60270 standard. Various amplitude and power density spectrum descriptors are proposed, as well as PD source type identification abilities on grounds of the selected descriptors are considerated. Electrical power transformers on-line PD detection and evaluation systems improvement and development are the main purpose of the presented research. Laboratory experiment results gives a solid base for further research focused on verification of the proposed methodology on a real life apparatus.
