| Abstract: | A new optical voltage transformer （OVT） without using quarter：wave plate is introduced; it is suitable for the measurement of high voltage. The design of the transformer is based on Pockets effect, but does not use 1/4 wave plate structure. Based on Jones matrix the mathematical model for OVT is set up, the optimum input angle and working point is designed, and the theoretic equations for the voltage and output intensity are derived. Comparison with traditional voltage transformer and associated experiments are made, the results show that this design is simpler in structure and higher in accuracy. |
