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.
