Background

The insulation resistance test belongs to routine tests of electrical equipment, and is one of methods for detecting insulation defects of the electrical equipment based on national measurement standards. For example, the measurement of the insulation resistance of a cable is to check whether the insulation of the cable is wet, dirty or has local defects. If the cable is wet or has local defects, its insulation resistance is significantly reduced. At the same time, the device under test must be de-energized from all sides and discharged to ground before testing the electrical insulation resistance. The measuring staff must be kept at a sufficient safety distance from the live part. The insulation resistance test usually needs to use a megger and a hand-operated generator, and during the test, firstly, a power supply is cut off, a circuit is connected in times, and a generator crank of the megger is rotated clockwise, so that the voltage generated by a generator rotor is used for measurement.
