| Abstract: | Compared with traditional IEC method,the wide bandwidth pulse current method could get more information about partial discharge,which will be helpful to improve the sensitivity as well as the ability of anti-interference.This paper study the pulse quantitative determination technology used by partial discharge detection based on wide bandwidth pulse current method.The design principle of pulse calibrator is introduced and the wave and spectrum characteristic of calibration pulse is analyzed.The accuracy and linearity are tested.The equivalence of two methods is proven by partial discharge practical partial discharge measurement. |
| Keywords: | partial discharge wide bandwidth pulse current quantitative determination calibration pulse |
