Abstract :
The present work concerns the partial discharge (PD) activity in simple insulating system (twisted pairs) when switching voltage waveforms are applied. A special low frequency PD coupling system allowed to determine two quantities indicating the stress actually connected with the PD activity. Such parameters have been considered to determine life prediction models
