TRANE Stealth Chiller Circuit 1 AFD 1A Bus Under Volts | Part 2 Results Are In ⚡️🦎 

Awesome, Thank you! 👊

⚡️yep

I like that Stealth Mode 👍 The apprentice is doing well, today is his 1yr anniversary in the trade 👊

Thanks Dylan 👍

Thanks SilentoneVictor 👊

Thanks

😀 Thanks for the support 👍

Thanks Steven 👍

Thanks for watching 👍

Ha, we do have our share of power issues especially when storms roll through. Thanks Jason !

Thanks, it’s VFD Semiconductor Fuse Type FWH-200B (200 amp)

It’s not just for lug nuts 🤣👍

Good question, on 3 phase like this one Trane recommends 0.2 to 2.5 ohms DC resistance of windings be within 5-10% of each other. Thanks 👍

Yes its 150 Ton chiller with variable speed compressors

Good question GRC, because one good reading doesn’t mean something isn’t wrong. However, one bad reading guarantees something is wrong. Thanks for asking 👍

Agreed, 100% correct after verifying winding resistance on a three wire motor, test one leg and you tested them all. But, it doesn't take much time to do the other two and the one time someone doesn't check all phases is the one time they didn't measure the winding resistance correct and there is a bad winding. So not losing anything by doing all three but a minute or so.

lol you perfectly encapsulated the lack of real life problem solving engineers are known for

Stick to your clipboard and computer programs. Let the big kids handle the work in the field - where the real problems are solved.
