Dual-end electrostatic film vibration voltage transformer

ZOU Yang;XU Qifeng;Fuzhou University;  
A kind of DEFVVT( Dual- end Electrostatic Film Vibration Voltage Transformer) is designed,which measures voltage by the micro-vibration of electrostatic film. The functional relationship between measured voltage and film vibration is deduced,according to which,the recovery method of measured voltage is given. The application of high-precision micro-vibration detection in DEFVVT is introduced. The simulative results by Simulink show that the measurement accuracy of the designed DEFVVT reaches grade0.2,its transient bandwidth response is better and its response speed is higher. Experimental results show that,from 80 % to 120 % of the rated voltage,it has good measurement linearity and its measurement accuracy is close to grade 1.
