Ultra-high-frequency Detection Technique for Partial Discharge in Oiled-paper Insulation
摘要
Abstract
Conventional on-line detection methods of partial discharge are interfered by surroundings, therefore some simulation models of typical partial discharge in transformers are constructed in laboratory, and the models are measured by both UHF narrowband and UHF wideband detection systems. The measurements indicate that for the UHF narrowband detection technique, the central frequency and the bandwidth of the measured signal are adjustable, so optimum central frequency and bandwidth can be selected to avoid interferences; and the UHF wideband detection technique can detect much partial discharge information due to its wider frequency band.关键词
