What is Research on Non-contact Voltage Transducer for High-Voltage Transmission Lines Based on Inverse Problem of Electric Field about?

## Abstract A new method to measure the voltage in a grid has been proposed based on the studies of a novel electronic voltage transducer for the high-voltage power transmission equipment using the charge induction principle and electromagnetic computing method. The voltage measuring method has been improved, the real-time electric field position and orientation near the high-voltage transmission lines has been measured and the real-time voltage has been calculated by computing the electric field inverse problem. According to the electric field simulation with test data, the data compensation and calibration calculation were carried out. With the rapid engineering method on computing voltage, a non-contact electronic voltage transducer has been developed. First, we did the confirmatory test of the electric field detection and designed the preliminary model of the sensor. By the contrast test of voltage detection, the sensor was able to realize the voltage detection, but the precision was not high enough. Next, the measuring mechanism of the voltage transducer was analyzed taking account of strong interference from electromagnetic field, electric field distortion, changes in tempera
