摘要：

A wide-band voltage measurement system is proposed to optimize voltage monitoring on power grid based on capacitive current. Capacitive device leakage current components in frequency bands of 30Hz similar to 3kHz and 3kHz similar to 1MHz are acquired respectively by two inductance coils, whose magnetic permeability are different. Then wide-band voltage of 30Hz similar to 1MHz is rebuilt based on two paths of signals. This paper introduces the components of the measurement system, and optimizes component parameters to ensure sensors' amplitude and frequency characteristics. Experiment results verified that the measurement system has good accuracy and linearity in the measurement of power frequency voltage, the switching overvoltage and the lightning overvoltage.
