| Abstract: | Optical Fiber Voltage Sensor can be applied to monitor and measure the voltage of the power network. In this paper, the principle of Bulk Optical Voltage Sensor is pondered and the influence of all parts of sensor head on measuring range and nonlinear distortion is analyzed, and the way of improving SNR is acquired. Through the study the linear measuring range of the virtual value is greater than that of the instantaneous value is known ,when the monitored voltage is alternating sine wave. Finally the optimal alignment of all parts by which the topmost SNR and the minimum nonlinear distortion can be acquired is determined. |
