Megging a motor is a term used to test a 3 phase motor to check the resistance and condition of the motor windings using a megohmeter. These type of motors produce an electrical charge to conduct a resistance reading. If there is a low amount of resistance in Megohms then the motor may need to be serviced or replaced. This test used for preventative maintenance.

Thanks, Katie. Short, to the point, and easy on the eyes.
Gross dude
Thank You for a good demonstration. The audio was nice, crisp and clear.
Warning! There is no-one like Katie in this industry.
Beautiful presentation literally.
Thank you for your kind words
😁
Make sure you have nice ground connection, she put crocodile on paint 🤭🤯
Yes but that was ground on the housing so she really had not other choice.
Excellent presentation!!
very useful
+Alvin Andal Thanks!
fieldwindig
Nicely explained, thank-you.
Welcome
Tech plus a smart girl, excellent ;-) Thank you for this video.
Excellent
Can you share motor configuration with Unidrive so 1405 and also parameters needed
hello,a question should not we disconnect the star point connection prior to measurement?thank you
No
Great job. Now I can do mine. Lol
Good
A friend said his father used a megger to hunt for worms in the mud for fishing !
Some Megger's can generate a lot of voltage. He probably has a 1000volt range on it and it might make the worms want out of the ground if it is shocking them, eh?
Thanks mam
Hi There, great video. I was wonder if you can answer this question. I don't have a megger for testing 3 phase motor. However I am testing phase to earth and getting a reading of 1.000 ohms. Is this normal? I was taught that I should not get any reading on ohms going from phase to earth. I am getting mixed information in the field. Any info would be appreciated.
That sounds like a bad reading to me. Compare that measurement to the other phases/coils.
Bad motor
Bad motor but make sure you have all motor leads disconnected from each other
Thanks mam beautyfull your my favorate and crash teacher lol hehehe😂😁😀
What about phase winding isolation and testing phase to phase insulation?
Phase to phase windings are connected together at each motor terminal and are very low resistance. As for "phase-isolation", if you are referring to the windings staying insulated apart from each other, that would be done with an Inductance and milliohm meter. This Video was to demonstrate using a Megohmeter to test a motor that is all.
You have a point.
I was taught to separate the windings
when doing the meg test to ground.
@@GalcoIndustrial Could you explain that process?
@@GalcoIndustrial bollocks, should have tested Phase to Phase with a merger.
سلام بدي قديش بيعطى كهرباء وين الشركه من فضلكم ابعتولي رقم الشركه
Yeah it had a hand crank on it , sounds easier then shoveling!
imho, she should NOT rest her palm on the live circuit (motor body) under the test. bad example video
Huh? Didn't show the readings, nor explain PASS / MARGINAL /FAIL .
ppe
If your asking what this means, PPE usually stands for Personal Protection Equipment.
😃😃😃😃
Beautiful women
Thank you
Were you a stewardess? Sounds like it
You mean a Flight Attendant,,, nope
Generally? Seriously? What about Phase to phase readings? A lot of motors can't be megged to ground. Only phase to phase. Ohmeter for ground fault.
Well a Megger is only for phase to ground testing. To do phase to phase you will need a very different piece of equipment. Capable of measuring very low resistances and inductances. A 1HP 3 phase AC motor will have some measurable ohms phase to phase and should be balanced with in 10% or less (a new motor may measure less than 5% variation). At about 10HP and up, you will measure less than 1 ohm of resistance phase to phase.
GalcoTV. You CAN megger phase to phase. Just lift 3 of the 6 tails and test away.
But it's rare to bother with this procedure. Cos normally just megger the whole unit and it's either a pass or a fail.
