本文提出并建立了一套数字化的高压断路器电弧电压测试系统。通过采取措施，该系统能有效地工作于强电磁场干扰环境中，并在燃弧过程中定量测量电弧电压波形，在电弧熄灭后安全耐受暂态恢复电压。　　在电弧电压测量过程中，承载大电流母线所产生的压降迭加在电弧电压上，通过采取硬件补偿措施，将母线压降抑制到最小，使被测电弧电压得以最大限度地增强，因而该测量系统能定量测量电弧电压。

A set of digitized measuring system of arc voltage for high voltage circuit breaker has been set up successfully. It functions normally even in the environment of an intensive electro-magnetic interference.It can get the waveform of arc voltage accurately during the arcing period, and withstand transient recovery voltage due to the extinction of arc. When the arc voltage is measured, impedance voltage across the two measured points shall impose on the arc voltage. Through high precise compensation, the influence of impedance voltage on the arc voltage is limited to the minimum, gaining the desired arc voltage as far as possible. Therefore, the accurate arc voltage can be obtained through this system.
