Nowadays, the optical voltage sensor (OVS) has become the best practical solution for the high voltage measurement in modern smart grid. And the polarization of the incident light greatly influences the sensor's measurement accuracy. In this paper, taking the radial polarization optical voltage sensor (RPOVS) as an example, its practical optical model is established by using the theory of polarized optics. The formula of the measurement relative error is obtained, and the influences of the ellipticity and extinction ratio on sensor performance are analyzed in detail. Then the suggestions are given and verified by simulations and experiments, which show the measurement error brought by the polarizer parameters to RPOVS is reduced by about 0.2%, promoting the sensor's realization of 0.2 accuracy class from the aspect of optical path. In addition, this study has certain reference value for other types of OVS and optical polarization measurement. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.
