The following characteristics need to be pointed out:

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.

① Rated output voltage: 30KV

②. Output frequency: 0.1Hz, 0.05Hz, 0.02Hz, 0.01Hz.

③, carrying capacity:

0.1 Hz maximum 1.1µF (theoretical value, field cable length is 3-8 kilometers)

0.05 Hz maximum 2.2µF (theoretical value, field cable length is 3-8 kilometers)

0.02 Hz maximum 5.5µF (theoretical value, field cable length is 3-8 kilometers)

0.01 Hz maximum 11.0µF (theoretical value, the field cable length is more than 10 kilometers)
