Abstract: (1510 Views)
In this paper, an efficient method is proposed for the temperature compensation of optical voltage sensors. In this method, the x-cut LiNbO3 bulk crystal with optical path parallel to z-axis with two orthogonal output signals is used. By using the two output signals and the compensation algorithm, the effect of the temperature and laser intensity was eliminated, and the electric field intensity parameter was measured with high accuracy and the mean error reduced by %1.3. This method has been successfully implemented in order to solve the temperature challenge in optical transformer, designed and constructed by the Niroo Research Institute (NRI), were successfully implemented after passing the industrial tests and ensuring their reliability.
