How to test 3-phase motor using MEGGER. Winding resistance and insulation test.

In this video you will find out how to test 3-phase induction motor. For tests we'll use MEGGER MIT 310. We'll learn how to identify windings, check windings resistance and insulation resistance.

Could have been a good video with some verbal instructions instead of that obnoxious music.

[@RR42636]

Hey man, just some constructive feedback. From a visual standpoint, it's a good high resolution video. The cheesy music and all the flashy animations just take away from it though. You'd be a lot better off with just a simple narration of what you're doing. Thanks for the video in any case.

[@davehogan1716]

Agree

[@shmeet298]

I think the videos better without chatting shit and boring us. Was great thanks for the video

[@suckL3m0n5withGeoffreyFirmin]

Hey man, just some constructive feedback. Not everyone operates the same way as you do. Why not make some of your own videos?

[@drew21241]

Hey Iamzimbabwe36 eat a bag

[@zeeshanullah4296]

while doing insulation resistance ,megger was set to dv voltage ?

[@athilaldurry5880]

Many thanks

[@leejohnson197733]

So if I had zero between earth on one winding is that an earth fault and it needs rewinding

[@AboutElectricity]

That's right.

[@MLK.PaNoRaMa]

Can I use a normal multimeter for insulation test?

[@AboutElectricity]

No, but you can use simple multimeter to check windings continuity.

[@MLK.PaNoRaMa]

@@AboutElectricity what is cheapest meter option I can get tondo insulation test? From eBay..

[@AboutElectricity]

@@MLK.PaNoRaMa the one from the video is Megger MIT 310. But I dont know if it is the cheapest.

[@flippperboy]

So what happens when the motor is reading low resistance? Does it set off the overloads or burn the cables in the control cabinet?

[@AboutElectricity]

It triggers short-circuit or overload protection.

[@phania3077]

Unable see display clearly...

[@TT_S90]

When I measure coil resistance then should I select resistance mode in the megger meater?

[@ponmudipn1493]

Nice

[@JasonStevenRyan]

you didn't insulation resistance test between windings 2 and 3

[@AboutElectricity]

Jason Ryan Mea Culpa.You're right I have forgot to megger between the windings 2 and 3.

[@dvsandgo1]

Bruh i just had to say same comment lol

[@kylemailey7661]

@@AboutElectricity when doing between 2 different windings shouldn't you up it to 1000v?

[@lllCANDYMAANlll]

@@kylemailey7661 I dont know, I remember being told by someone to go double the voltage than what the motor usually runs on. Not sure if this is true?

[@ws392]

Like it!

[@ninofrancisespadero4567]

Is that >1000 Mohms?

[@dehareglemlem]

not clear what are done on the megger adjustment

[@AboutElectricity]

what part of the movie?

[@kingmuller5189]

where is the megger display

[@russelladams4558]

Hi jake

[@mohammadrafik6]

When select 500 volt that time also readings shows in ohms or voltage. Please explain

[@AboutElectricity]

When selected 500V means you are applying 500V between testing probes to do insulation resistance test.Resistance is displayed in ohms.

[@ChristianRamosELCRVEVO]

how do you know which winding is which?

[@AboutElectricity]

I checked the resistances at the ends of the windings.

[@lllCANDYMAANlll]

For me, they are always the same pattern, bottom left to top middle, bottom middle to top right and the lastly bottom right to top left. Never seen a 3 phase motor not configured like this.

[@RMQ23]

Sir only you can see the reading of your megger

[@Ackerman-iq3fl]

how to do it by a micro ohm meter ??

[@AboutElectricity]

The same way but you can't do insulation test.

[@AboutElectricity]

Hi ! Does this presentation deserve 👍 or maybe 👎 ?

[@जानजान-स7च]

Sir video me kuch bhi thik se displays me dilkh nahi raha he

[@AboutElectricity]

English please.

[@electricety]

Can you turn off the dam music and speak like a person

[@thameemansari2797]

U should be show some value man

[@chandrakantapradhan4963]

Megger reading is not clear

[@tripathi.harshmani]

kuch bol bhi dijiye sarkar..

[@avdhuri]

DUDE WHATS BACKGROUND INSTRUMENTAL

[@manojantony6118]

?????????

[@Mark-eu4di]

Poor illustrations, kill the music…

[@hardwarenetworking3308]

Nooo clarity

[@sandilemqolo3343]

This noise music behind the scene

[@dasroymohan7026]

Why no mouth talkimg?

[@dammikadammika5285]

😄😂

[@antoniotuvo1280]

horrible music. Explain what you are doing

[@meesiphht2769]

why would anyone that looked at this like it?

[@baburamvineet878]

Sir, It could be better if you test on actual cable.

[@qasimkazmi786]

Nice

[@alllink3823]

Nice
