With the development of the power system,the optical current transducer(OCT) has broad application prospects in this system.And filtering out the noise effectively,improving the signal noise ratio(SNR) are processing a more and more important part in the OCT signal processing.The Kalman filter algorithm theory is used,establish an appropriate model and simulate via LabVIEW to find a way to filter the noise out effectively and improve the SNR of the optical current transducer.
