摘要

Based on the photoelectric effect of partial discharge and the sensing characteristics of fluorescent fiber, this paper has employed a fluorescence fiber sensing system for detecting partial discharge signals in transformer. In this paper, the main components of the sensor and their parameters have been given. A combined detection of UHF and fluorescent fiber sensor for PD in transformer model has been used. The usage and results have been analyzed. The results show that the partial discharge pulses detected by the two methods occur around the positive and negative voltage peak under the needle-plate defects in a power frequency period, and the pulse number is consistent with the phase.
