In order to achieve the high-precision measurement of the post arc current in the breaking test, the paper proposed a novel post-arc current measuring equipment(PACME), which is based on the vacuum arc commutation and magnetic arc blow. The current commutation between the vacuum arc and the shunt resistor with ETMF was investigated. Based on the current commutation results, the vacuum arc commutation characteristic and the influence of the ETMF were obtained. Then the prototype of the PACME was designed and controlled by optical fiber communications. The duration which the main current absolutely flow through the shunt resistor is more than 20μs and the peak current of the shunt resistor is below 500 A below the measuring range of the high-precision current sensor, which meets the requirement of the post arc current measure. The bandwidth and accuracy of the PACME is 15 MHz and 0.3% respectively. The test results verified that the PACME is correct and accurate, which supplies the base for studying the post arc characteristic in breaking test.
