What are the precautions for measure the insulation resistance of capacitors

Measure the insulation resistance of capacitors,the following points should be noted: (1) A 500 or 1000 volt megohmmeter can be used to measure low-voltage capacitors, and a 2500 volt megohmmeter should be used to measure high-voltage capacitors. (2) The capacitor should be discharged before and after the shaking test to avoid electric shock accidents. (3) When [...]
