【Abstract】 The partial discharge detection in ultra wideband is a new technolgy. It has obvious advantages, but its detection theory is still not known very well. Based on theoretical analysis of sampling technology, a real time sampling technology for gathering partial discharge signal is studied in this paper. The operating condition and the sampling methods of the signal gathering system in different time base are analyzed in detail using a developed new detection system of partial discharge in ultra wideband. Finally, the importance of real time sampling in partial discharge detection in ultra wideband is emphasized. It is significant for founding the new theory of partial discharge detection in ultra wideband.更多还原
