Abstract	The temperature drift of measurement accuracy is one of the difficult problems in the practical process of optical voltage sensor. This paper presents a kind of self-healing optical voltage sensor technology to overcome above problem. The technology combines self-healing and optical voltage sensing techniques to realize the synchronous compensation of disturbing birefringence and the transistor half-wave voltage. This technology can realize the automatic compensation of temperature, improving the whole performance of sensor while ignoring the influence of ambient temperature. The experiments show that the linearity of the self-healing optical voltage sensor can reach to 0.2 grades in the room temperature. When the working intensity disturbances or sensor parameter drifts induced by temperature, the measurement accuracy of self-healing optical voltage sensor is improved largely compare to the conventional optical voltage sensor. The results show the validity of self-healing optical voltage sensor.
