Study on High Voltage Parameters Online Measurement Technology Based on Sealed Photoelectric Sensor System

In summary, there are two main issues facing high voltage parameter online measurement: obtaining of high-voltage side working power, and signal transmission between high and low voltage. To resolve these issues, we propose and design the high voltage parameter online measurement sensor system whose light source and light signal transmission is based on a sealed space. The sensor system contains high-voltage side power supply system and signal measurement and transmission system that are sealed inside a layer insulator. The sealed light source and signal transmission makes sure the high efficiency and reliability of power source at high-voltage side signal sampling and processing circus. It also guarantees the safety, reliability and accuracy of signal transmission. This article introduces the working principle, the structure and the design of the sensor system.
