Problems solved by technology

[0003] The electro-optic effect sensor is the core component of the optical voltage transformer. The research on it has always been the focus of domestic and foreign scholars. There have been many sensors based on different electro-optic effects, and the most widely used sensor is based on the Pockels linear electro-optic effect. The core difficulty of PT lies in the electro-optic effect sensor and the digital conversion of optical signal return. At present, the electro-optic effect sensor at home and abroad cannot break through the 12cm barrier, resulting in the detection distance of the measured object being limited to within 12cm. Therefore, to solve the above problems, a method based on Signal Acquisition Method of Wireless PT Based on Electro-optical Effect Sensing Technology
