How To Use Megger & Meg Motors

[@JD-hr6dr]

It's so nice to hear an experienced HVAC tech not mindlessly shill Fluke products for once. Great video, love the channel

[@HVACRTECH-83]

Fluke is among the best though and I trust them more than a cheap 2 or 300$ megger or even a multimeter, I've only ever used fluke multi meters. When your life is in the hands of a tool of any kind, I don't believe in saving money on on that sort of purchase. And I don't like seeing anyone else doing it either.

Hahahaha

Thanks! clear, concise,makes sense, easy to understand and hear, I am going to buy one right now !

[@sv6k0a39]

You are helping me tremendously in my career.

[@ramirosepulveda2306]

Excelent explanation!!

[@keepnitkool9042]

Thanks for the video, very informative. So is it best for motor to be at ambient temperature to use the Meg for a accurate reading?

[@HVACTIME]

Best to be at operating temp

[@vickynguyen7688]

Thanks for your video. Learn a lot from it

[@holy_diver5023]

Great video👍🏻

Thanks man for the whys and what to look for. Maybe I didn’t understand or missed it but what voltage settings do you use based on motors and their operating voltage?

[@HVACTIME]

never exceed 2x the rated voltage. so 460v motors I test at 1000v and 208v I test at 500v max.

@@HVACTIME thanks bud! Love your stuff.

[@johnnys3602]

Just to piggyback off of the original question because I've heard different things. Is this acv or dcv? I heard dcv but just wanted to confirm this. Thanks and great videos by the way!

Good explanation and good vid ...Thx ...

[@SgtTanPants]

Hey man, another great video. I got a megger when I started in industrial. Never used it much. Do you know of any charts showing the voltage settings and ohm ranges for different motors on different voltages settings? I really want to become more proficient with my megger.

[@HVACTIME]

I think Fluke has released some material but other than that I wish I did.

[@jasonjohnsonHVAC]

Megger test values vs motor voltage tests: 208v motor ( megger voltage 500 ) 460v motor ( megger voltage 1000 ) Industry standard is 1 megohm per 1000v That said what Holden states is what you should go by. I personally use the PI and DAR tests. They are timed tests that have a ratio value to show the condition of the leakage to ground aka insulation test. PI RATIO: 1.0-2.0 is questionable. 2.0-4.0 is good Greater than 4.0 is excellent DAR RATIO: less than 1.25 is questionable 1.26-1.6 is good 1.6 and above is excellent

@@jasonjohnsonHVAC thank you buddy your the man

[@TheEtbetween]

Thanks

[@Dog-whisperer7494]

1 megohm at 500vdc is the minimum acceptable range and is a pass, anything between 1 megohm and 2 megohm further investigation is required , we should be looking for a reading of 1megohm to infinity. Anything less than 1 megohm tells us there’s a problem with that equipment we are testing.

20 million 40 billion million….just say mega-ohm and giga-ohm my guy. 🙄
