    Abstract: In order to ensure that the output current is sinusoidal in circuit breakers tripping characteristics testing, this paper researched the testing method, raised the design idea of LabVIEW virtual detection technology with the microcontroller PIC18F4620 as the core phase selection device and gave the design process of software and hardware. The designed device was applied in the circuit breakers tripping limitation and characteristics testing to nicely eliminate the aperiodic component of currents, realizing the tripping characteristics testing with the functions of control, data acquisition, data processing and waveform display.
    Key words: circuit breaker; tripping characteristics; sinusoidal current; LabVIEW virtual detection technology; phase selection synchronous switch
