摘要：
This paper describes techniques for improving the accuracy and stability of the optical voltage transformers (OVT), which are affected by temperature, around circumstances. Higer accuracy and stability is achieved by two light-channels compensation method, which uses one polarizating beam splitter. Many tests show that this compensation method can eliminate the effects of unwanted birefringences induced by temperature and around circumstances of OVT effectively. OVT which uses this compensation methods has passed the type tests with accuracy and stability within +/-0.2%.
