The ferro-resonance test of capacitor voltage transformers requires analysis and processing of the test waveform，which is cumbersome and time-consuming to manually process. In view of this issue，a kind of measurement and control device for ferro-resonance testing of capacitor voltage transformers is introduced in this paper，which can control the short-circuit switch，automatically collect and analyze test waveform，automatically save test results and test waveform. The device is used in the actual capacitor voltage transformer for the ferro-resonance test. The result shows the measurement and control device，compared to the manually processed waveform，saves time of manual waveform processing and improves work efficiency.
