How To Properly Megger A Motor Webmotor Org This configuration allows the megger to measure the insulation resistance from the winding to the ground. figures 3 and 4 diagrammatically demonstrate the proper layout for a megger test for both an ac and dc motor, respectively. figure 3. typical megger testing layout of ac motor and associated starting equipment. image used courtesy of the. 17 december 2020. well, if we’re nit picking, technically speaking, you can’t ‘megger’ a motor. megger is a registered trademark, not a verb, but we get it – old habits die hard. plus, we’re flattered that you’re throwing around our name so much, so we can’t complain. but what you’re really asking is – how can you run an.
Megger Test Procedure For Motors Pdf Webmotor Org 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. Example: if a 230v motor is being tested, use the 500v setting on the megohmmeter. place one meter lead on the ground terminal or wire and place the other meter lead on one of the phase wires or terminals. press test on the meghometer. a very high resistance reading (generally greater than 10 megaohms) will indicate the motor insulation is good. Apply a voltage of 880 volts if the motor is rated 440 volts. testing the older motor at a lower voltage (about 80% of the twice operational voltage) is necessary. press the test button on the megger after setting the voltage as directed in step no. 3. the insulating resistance value should be recorded. if the megger displays a reading of zero. As part of our crane repair training course for overhead bridge crane technicians, we've made an instructional video on how to megger a motor and the proper.

The unit should be discharged at least four times as long as the test voltage was applied. the megger is capable of applying different voltages, and the level should be coordinated with the type of equipment under test and the scope of the inquiry. the test is generally conducted by applying between 100 and 5,000 v or more. Follow the manufacturer’s instructions for operating the megger instrument. connect the megger leads correctly to the motor’s terminals or leads. limit the test duration to what is necessary to obtain accurate readings. monitor the motor during the test for any unusual behavior or signs of overheating.
