Research on the measurement and controlling system for synthetic making test of high-voltage circuit breakers at full voltahe

According to the newly emended international and national standards, full scale verification of the short-circuit current making capability is required for high-voltage circuit breakers. On the basis of the realistic conditions of test-station in China, the emphasis of this study lies in the design and realization of the measurement and controlling system for the synthetic making test, which include data acquisition, signal processing, data communication, EMC design and system performance verification etc. The control strategy and main factors that affect controlling accuracy are analyzed. In the end, the hardware structure and software design are also presented.
