摘要
介绍了一种新型的光纤电压互感器,针对FBG传感器在现实应用中的温度和应力的交叉敏感问题,设计了一个光纤双光栅温度、电压测量系统,对光纤双光栅的温度和电压传感特性进行了初步的实验研究。
A novel design of a fiber-optic potential transformer is investigated. This paper deigns a temperature and voltage synchronous measuring system using the dual-FBG to solve the problem of the temperature and strain measuring of cross-sensitivity.Initial test was done to study the temperature and voltahe sensing characteristic of the dual-FBG .Experimental. results show the temperature and strain sensitive characteristic of the dual-FBG.
