HVACR: "Megger" Insulation Test For 3 Phase Compressor (Motor Windings Insulation Test) SUPCO M500
Vložit
- čas přidán 5. 09. 2024
- Today we will be performing an insulation test (Meg a Motor/Megging a Motor/Megger a Motor) for a 3 phase air conditioner TRANE compressor using the Supco M500 megohmmeter. We are looking for 100 megohms and greater according to this meter as well as a general rule of thumb to diagnose the motor as good. We are checking the insulation surrounding the motor windings.
The Supco M500 Insulation Tester/Electronic Megohmmeter is an alternative to taut band megohmmeters. It gives you accurate and fast measurements to verify the condition of insulation. As it comes with a soft carrying case, The Supco M500 Insulation Tester/Electronic Megohmmeter can be used in applications such as testing motor winding insulation and diagnosing heat damaged and deteriorating insulation in hermetic refrigeration compressors, appliances, panel boards, relay control circuits, motors and more. Measure insulation values up to 1000 megohms @ 500VAC.

Nice explanation but get your camera angles set!
Nobody can see what you doing. The camera not focus where you working.
Camera angles were a bit tough to see in some clips as I was wearing a camera on my head but if you listen and watch you'll understand exactly what to do. One lead on a compressor terminal then the other grounded to the compressor casing. Repeat for all 3 compressor terminals (Start, Run & Common) I will make another video that is clear to see. Thanks for watching & stay tuned for new videos every week🔧⚡️
I know how do it. I got the supcoM500 and use it every day. Just some people understand visual more than ear. Sorry if im offend you. God bless you
Interesting and important material to know. Thanks for info JMT.
Thank you Mr.Tech! Appreciate you watching & supporting the channel🙏 Stay safe out there & stay tuned for new videos every week🔧⚡
Got one of those instruments, used couple times and it checked good. Here is my scenario, got a burn out compressor and I was showing my helper how a new compressor will read, oddly enough the new compressor also checked bad insulation, not grounded obviously. It left scratching my head. We went ahead and complete the replacement. It ran and was doing its job.
Just sharing what I found. Feel free to post if you seen a compressor like it.
I have a special place in my heart for the old XE Trane condensing units. They were so good and lasted very well. I work on quite a few to keep them going. Newer units aren’t anywhere near as good. I’ve seen compressors bad right off the get go. Absolute shame in quality.
I hear that! Appreciate you watching & your response🙏 It is a shame how they don't make them like they used to but this is everywhere with every manufacturer. Can't complain, keeps us in business😁 Stay safe out there & stay tuned for new videos every week!
I used to love how to do the self-test by jumping to do terminals on the on the top going to the stages
8 on the serial designates 1998 on Copeland compressors. First 2 digits designate the year it was made good indicator it was ever replaced or warrant
Great job as always. Thanks for sharing your knowledge with us. 👍
U can get a good ground on refrigerant lines
Привет!! Жить или умереть!😂
Beautifully done.
You should be a licensed hvac tech with epa, but checking electrical you don’t need 608 certification. Only if there’s a possibility refrigerant could be released
Hilarious bro You're like Spider-Man of the Hvac multiverse!! thanks for ur videos, learning a lot
Yeah with today's safety guidelines you can't be jumping up and down on boxes like that to serious issue either customers to set up a ladder or you have to bring up your own extension ladder The good old days are gone
Good job there...I just got me one and it makes the job alot easier to troubleshoot

I just go the Klein et600 and this thing is awsome test with accuracy up to 1000 volts.
yo is it true this megohhmeter isn't really the right way to test the compressor ... since each company lists what's considered the lowest amount the compressor can function on ?? I just watched a video where the tech was showing this. like the megohhmeter condems compressors when they really work because it's based off the megohhmeter rating not the actual compressor manufacturers
great professional work bro
Thank you brother always thankful for your support! Stay safe out there & stay tuned for new videos every week!
Didn't know ''Acrobatics'' was part of HVAC/R training ... Lol ... Good vid ... Thx ...
great job as always. keep going
Thank you Simo! Appreciate you watching & stay tuned for new videos every week! 😎🙏🔧⚡
The bottom component isn't thermal overload. It's a well heater. Fyi.
Safety last
Haha sometimes🤣 Thanks for watching Craig! Stay safe out there & stay tuned for new videos every week!
I'd have to say the live, dead, live test is safer and before using that method, test meter leads by switching to ohms/cont. and shorting leads. Don't forget to change function to volts after checking leads. Now who you think is going to all that trouble?
Very nice explanation, I am happy to follow up with you
If your a real hvac tech with years of experience you can meassure any compressor with a clamp multimeter or any multimeter...
You definitely can but sometimes the meter won't show you if a compressor is shorting, that's were a megohmeter comes in handy
"You should have EPA license before touching any type of equipment that has refrigerant" - only if you are a tech by trade. You have to pass an EPA-approved test to earn Section 608 Technician Certification, for under 5lbs appliances type 1 you can do it online. You don't have to be a section 608 technician if you service your own HVAC. Under Section 608 of the Clean Air Act, EPA prohibits individuals from knowingly venting refrigerants containing ozone-depleting refrigerants (including HCFC-22) as well as their substitutes (such as HFCs, including R-410A). That's it. Free to add R22 if you are a homeowner, free to evacuate. You will not be able to buy R410 in your local store without 608, but get Type 1 Open Book Certification online and problem solved. Or go ebay
In the proccess using Skillcat for my epa 608 cert and all the other training they have
so i can start working on our warehouse hvac.hopefuly there legit. Ive learned alot from the hvac guy who was willing to teach me. Repairing/servicing Almost 100 rtu units. my boss wants me to start doing basic troubleshooting/repairs like fan motor swaps/ anual testing/cleaning. If they dont give me mofe money ill go somewhere else. The hvac guy already said should do well in hvac from what ive helped him with so far. I can unnoficialy do car ac repairs so its time to move up to the big boys
Man, you have a Russian tattoo on your hand but your English is perfect:-))
I'm working on a similar trane compressor I get good readings on run and start but I get no reading at all on common what does that mean?
Looks like BK. Ave T or somewhere back there. Great vid.
Nice video man !!
Thank you bro! Appreciate you watching🙏🔧⚡
great explanation, TY🌟🌟🌟
Thanks Great video. God Bless
I’m curious if this megger works properly on 460v equipment. Aren’t you supposed to apply double the voltage to the winding? So in this case this is a 230v 3 phase RTU. That megger applies 500v so that is double of 230v but what about a 460v compressor? Shouldn’t you be applying 1000v to a 460v compressor? Just curious. I was thinking about purchasing one of these meggers. Nice video 👍🏻
Klein et600 megohmeter does 1000 volts
Nice job. Yep they dont make anymore good quality compressor unfortunately.
Thanks for sharing
Can we get an accurate reading by Hooking up the wires coming out of compressor instead of terminals ? It Does Matter?
That would not exactly be an accurate compressor reading because now you are measuring the wires AND the compressor. A damaged wire could fool you into thinking the compressor is bad. Thanks for watching!
Stay tuned for new videos every week 🔧⚡️
@@JumpermanTech Thanks alot. Excellent video like always.
@@MrJeromegon You're very welcome! Anytime 🙌 Thank you so much 🙏
That tool is useless for Copeland scrolls, they state that a good reading is 0.5. You need a fluke to test lower than the 20 that the supco goes to.
Where did you learn English so good?? Nice Tatoo on right hand)))
In what state you are working? Maybe you need a helper?)))
You live in New York?
Ur meter shows number 20 to 1000 which means 20mega ohms or 20kilohms .y my question is ir value is 1.43mega ohms .
hello
Love your work but am facing a problem
I dont know The English very well so can you please translate it to Arabia
I reccomend saving up for a real megger bro, these supcos are notorious for bad readings, another tech i work with used to use one and he would test a motor that tested out good according to the supco and my fluke said otherwise on multiple occasions. Ive heard same bad things from other techs as well. not worth it, why do you think theyre so cheap? Gotta ask yourself why they cost hundreds less than a proper megger. Be safe.
Yes you will need a better mega when you're testing commercial industrial units which cost a lot more money😊
looks like you 16 for doing this old school style lol
Lol what? Thanks for watching bro!
you climbing and jumping
Not ! ITS NOT STRANGE .... All most all manufacturers are building things to break down prematurely, Except China , with China you just need to look at it and walk away quietly , and forget about sleeping well.
I've had brand new lennox units with US Motor for the blower literally burn out the idf motor in less than 8 months everything was within the rate RLA on commission and even when replaced with another US Motor that one burnt out in lime 6 months. Will never buy another US Motor again.
You may have power surges or just look further
dont really trust that cheap Supco megg tester, be a little more PRO with a real Megg Meter, instead of that SUPCO, KLEIN has an affordable Digital Meg Meter, and use a ladder
Yeah you better use a ladder
