The following characteristics need to be pointed out#65306;
Data of current and voltage are obtained directly through the sampling of high-pressure side and it is true and accurate.
Over-voltage protection: the instrument will shut down to protection within 20 ms when the output voltage is exceeding limiting values of setting.
Q&A:
How to choose the voltage level of the ultra-low frequency high voltage generator when doing the cable withstand voltage test?
"Ultra-low frequency high voltage generator" is mainly used for non-destructive insulation withstand voltage test of wires and cables. There are many domestic manufacturers of "Ultra low frequency high voltage generator", and different equipment is selected according to different cables.
