This paper describes techniques for improving the accuracy and stability of the optical voltage transformers (OVT), which are affected by temperature around circumstances. Higher accuracy and stability is achieved by two light- channels compensation method, which uses one polarizing beam splitter. Many test show that this compensation method can eliminate the effects of unwanted birefringence induced by temperature and around circumstances of OVT effectively. OVT which uses this compensation method has passed the type test with accuracy and stability within +/- 2 percent.
