| Abstract: | An optical voltage sensor based on polarization modulation is studied. Jones matrix is used to obtain the mathematical model and the compensation technology is used to eliminate the error owing to birefringence effect. The high precision shielded transformer is introduced to enhance the signal-to-noise ratio. The experiments demonstrate that measuring error is reduced to 0. 92%. |
