Insulation note capacitor

game gameMeasuring insulation resistance test capacitor matters needing attention:

1, the series capacitor electrode on shell insulation, low end coupling capacitor insulation to ground with 1000V megger measurement, the rest with 2500V megger measurement.

2, using the megger measurement should pay attention to in the measurement of both before and after the deal with the full discharge of capacitor; the measurement process, should disconnect the megger connected capacitor stop shaking handle megohmmeter, lest the capacitor charge and discharge damage to anti megger.
