Abstract

In order to measure the transient electric field in high- voltage substations, the electric field sensor has to be developed. The active sensor has been developed. In this paper a novel passive sensor is presented. This design is based on the study of the transfer characteristic of the spherical transient electric field probe and the analysis of the traditional passive sensor. As for the spherical probe, the relation of measurement capacity and the induce voltage can be used to select the measurement range. For the passive sensor, the differences of the detection methods of sensing signal is analyzed. When it is directly used to measure the transient electric field in the high-voltage substation, the drawbacks are pointed out in this paper. Based on the former analysis, the advantages of the novel passive sensor are summarized.
