Electrical performance test technical status related to the connector
contact electrical parameters of the main detection by the voltage, current transformers, data acquisition card and PC to complete.
Through the improvement of the traditional AC contactor connection and breaking test device, the use of single-chip microcomputer as a test device control module control AC contactor on and off
With the continuous improvement of the level of electrical testing, SCM more and more applications to the detection and control of various types of electrical appliances.
The collected data is Fourier transformed, and the time domain signal is converted into a frequency domain signal to calculate the phase of the voltage and current, and the power factor is obtained
