Digital realization of optical fiber voltage transformer based on virtual instrument

For the demand of digital transformer substation, with the help of virtual instrument technology, signal detection platform is constructed on optical fiber voltage transformer, which is based on the crystal Pockels effect. And then Ethernet interface is realized through the platform. As a complete set of detection system, this detection platform has an excellent man-machine control interface. It can provide not only real-time monitoring and online control, but also standard Ethernet interface for secondary equipment, which meets the requirements of intelligent one side equipment and network of secondary side equipment in digital transformer substation.
