提高光学电压互感器测量精度方法的探讨

A study on improvement of measuring accuracy of optical voltage transducer

提高光学电压互感器测量精度的方法,包括选择合适的电光晶体,利用退火法消除自然双折射的影响,利用双晶体或旋转反射法进行温度补偿以及双光路温度补偿等。由于有许多的因素影响测量结果,必须多种方法综合运用,才能达到较高的测量精度。

The methods for improving measuring accuracy of optical voltage transducer are presented, These methods include selection of suitable electro-optical crystal, eliminating natural birefringent influence with annealing method, temperature compensation performed with twin crystal or spinning reflector method and double light path compensation, etc. Since many factors will affect the measuring results, a higher measuring accuracy can be obtained only when multiple methods have been employed.
