Influence of Insulation Gas Pressure Change on Accuracy of Optical Voltage Transformer
Miao Ye · Transformer · 2001
The influence of the insulation gas pressure change on optical voltage transformer couldn't be neglected. It's a new problem created by the new sensing principle. This paper has analyzed the reasons and patterns of the influence and given the methods to reduce the influence. Both theoretic analysis and experimental results show that the influence of the insulation gas pressure change on the accuracy of optical voltage transformer may be reduced to ±0.1%.
