How To Megger A Submersible Pump Motor Youtube Meggers are used for quickly troubleshooting a well pump motor's resistance to ground. chris shows you how to megger a motor and explains why it is far super. Learn how to determine if a motor is good, grounded, shorted, open winding and mixed leads all with a multimeter. additionally, understand insulation resista.
How To Check Megger Value For The Submersible Pump Motor Youtube Electric motor research. oct 15, 2007. #7. when you 'meg' a motor, you are no longer testing for a perfect open circuit, but instead testing the slight leakage current that is always expected from a real insulation system. it is critical that you not meg at too high a voltage, because doing so can damage the insulation system. Mike farrar of preferred pump explains how to megger a motor.you can download page 62 from the grundfos manual referenced by mike in this video by clicking h. The voltage readings should match the specified voltage requirements of the pump. if the voltage is incorrect, check the power supply and wiring. overload relay test. the overload relay protects the motor from overheating. to test it, manually trip the relay by pressing the reset button. the relay should trip and cut off power to the motor. To assess the insulation quality, a megger tests a wire by exposing it to a high dc voltage for a predetermined time. in general, the process of testing a 3 phase motor with a megger is easy: turn off the motor’s power source by flipping the circuit breaker. set the megger to ohms and then check the leads to check electrical continuity.

Step 2. connect the megger leads between one stator terminal and motor body. step 3. apply twice the motor operating voltage between one phase and the motor body. if motor rated voltage is 440 volts, apply voltage 880 volts. we should test the older motor at less voltage ( about 80% of the twice operating voltage). step 4. It’s always better to disconnect component parts too and test them all separately, so you can know precisely where a weakness exists. for dc generators and motors, you’ll need to raise the brushes, as shown in the figure below. you can also test the rigging and field coils separately, from the armature itself.
