Paper Abstract

For many defects existing in the traditional voltage converter, a voltage probe is constructed by sticking a FBG on a PZT bar and the FBG sensor is demodulated with a CWDM based demodulation scheme and the high potential monitoring is realized. The FBG dynamic demodulation principle is introduced in this paper. The dynamic performances of the system were verified through experiment. The system repeatability is not worse than ±4% although there is no any kind of compensation based on data analyzing. A new realizable method was proposed in this paper.
