Ultra-low frequency insulation withstand voltage test is an alternative test method for the power frequency withstand voltage test.The test procedure is greatly reduced, which is more advantageous than the power frequency test. It can be widely used in the AC withstand voltage test of cables, large high voltage rotary motors and power capacitors.This product combines the advanced technology of modern digital frequency conversion, adopts microcomputer control, step-up, step-down, measurement, protection fully automatic, and can perform manual intervention in the automatic promotion process. Because of the full electronic, the volume small weight light, large screen liquid crystal display, clear and intuitive, and can display the output waveform, print output test report. In addition, the following features need to be specified:
