Abstract The instantaneous tripping of the over-current protection circuit breakers
should comply with the standard GB10963《Circuit-breakers for over –current
protection for household and similar installation 》 and the standard GB14048.2《loew-voltage switchgear and control-gear-low-voltage circuit breakers》.The common test
systems for instantaneous tripping usually employs photosensitive recorder,
instantaneous peak value meter or data collecting and controlling apparatus. But these
methods all have disadvantages besides some stongpoints. Thus another test system
is introduced in this paper ,which can be generally used and has the advantages of
easy operation and authentic report. The system has been applied in the laboratory for
a year and has presented a good performance.
