光学电压互感器晶体双折射误差的分析与抑制
Analysis and restraint of crystal birefringence errors in optical voltage sensor
摘要
Abstract
The birefringence errors of Bi4Ge3O12 crystal restrict the accuracy of the quasi-reciprocal reflective optical voltage sensor (OVS). According to the parameters of the optical instruments, their Jones matrixes and the mathematical models for the optical transmission of OVS were built. The influences of the crystal birefringence error on the system performance are calculated by simulation based on the proposed model. Additionally, the solution for suppressing the offset of the system crystal birefringence output is derived by filtering algorithm, and a high-pass filter to restrain the digital output is designed. The experimental results indicate that the designed high-pass filter does not change the static performance of OVS, but it can suppress the output drift caused by crystal birefringence, and improve the precision of OVS.关键词
