7 Images to Help You Learn How to Use a Megger for Simple Testing of Three-Phase Motors

1. Choose the appropriate megger: If the rated operating voltage of the motor being tested is 380 volts, then we can select a 500V megger. 2. Place the megger flat, perform a short circuit test by shorting the two probes, and if the pointer approaches 0 while cranking the handle, it indicates good condition. 3. … Read more

Using a Multimeter to Determine the Condition of Electric Motors and How to Measure Them

Using a Multimeter to Determine the Condition of Electric Motors and How to Measure Them

1. Short circuit to ground in the motor: The testing method involves connecting one end of the megohmmeter to ground and the other end to the motor terminal. If the insulation reads zero, it indicates a short circuit. 2. Open circuit between windings: The testing method involves connecting the megohmmeter to the two motor terminals. … Read more
