Research on Non - contact Voltage Measurement Technology Based on Near Field Detection

The construction requirements of the global energy internet greatly promote the information-based and intelligent development of electric power equipment. As the important component of electric power equipment, voltage transformer adopts the double-side detection method. As a result, the transformer is large in volume and weight, and inaccurate in detection, etc. With regard to the existing problems of the current voltage transformer, the non-contact voltage sensor is proposed on the basis of the near field detection method in this paper to achieve the voltage detection in power transmission line and other electric devices. New method and means are provided for the voltage detection of electric power system, contributing to promoting the information-based intelligent development level of electric power equipment in the global energy internet construction.
