I got to fix the same kind of VFD for a city nonpot supply. The normal techs they hire charge $3k just to show up + the cost of the actual repair (likely replacement of the VFD). My friend who works for the water department said I am pretty handy, so the city hired me on as a contractor. I take a look at the VFD and it is faulting for overtemp. No fan spin, so I crack it open and find the fan motor failed. I picked up new ball bearings at Grainger, and the next day I had it fully up and running again. City was thrilled, and I charged them $1k (I threw in the ball bearings for free lol). I also fixed a burned out contactor in the electrical box, but I didn't charge them for that (mainly because I forgot to lol).
One of my favorite parts of my job is that when I’m on top of my game, solving complex problems, and earning my pay, absolutely no one knows what the hell I am doing. The customer just cares that the equipment is making money, my boss only cares that I’m billing hours, my family only cares about when I’m coming home, and I’m over here nerding out on 4-20ma, instrumentation, ladder diagrams written on papyrus, and control logic.
I just got into this industry, more on the plc progtamming, troubleshooting, and repair side of things. Channel popped up out of nowhere, very relevant. Keep it up. Its like the AVE of automation controls repair.
I just retired from the AT&T power crew, slightly different equipment than I worked on but close enough to understand what you're talking about. Good stuff, love your commentary. Keep up the good work. Subscribed.
We made a cricket ball out of a 4700uf capacitor covered in rags and tape, with the 2 leads coming out about 1cm apart. Charge with 500v megger and throw to the fitters. Oh then run.
Nice to see from across the big pond, that sewerage operators worldwide would rather call out an electrician than check if the pumps are blocked. At this point I think they are afraid to let the poo slingers touch anything with VFD in case idk they break it?
Wait until the millwright tells you to jog it in reverse to clear it and you tell him its not a good idea but he insists so you do it and the impeller come's off the shaft oh well the motor and drive is fine😁. call me when you got it cleared and back together and remember not to chew your fingernails🤣
Not 100% sure this is European color coating, or its extremely dirty? Here in Europe we have brown,black,gray as the phases and usually for 3 phase in that order to get a right turning field.
As a Level 38 Certified Clipboard Warrior, with 6-Sigma endorsement, I did not see any cold work lock out tag out permit or locks, badging or mention thereof. No pilot, co-pilot documentation, 2nd level approvals or any of the necessary paperwork to keep clipboard warriors employed. Simple, basic understanding of electrical work and safe common sense practices is just not enough!!! -Nice work!
the dieless crimper might be a very good option, but it's very ugly for me. But that's just the opinon of a cabinet builder. If they are going to look like a birds nest of wires most of their life, they should at least look nice and pretty when they leave the atelier and get installed.
I've used a lot of AC-TEC ones I like the memory chip to store the parameters for the challenged electricians that cant program the drives. The Siemens AOP for the 440's does the same thing for their drives and you can save a couple of drive parameters in them just in case someone hoses the parameters up on you.
So maybe I don't know what I'm talking about but couldn't they just have turned the pump shaft by hand to diagnose a possible obstruction before calling the electrician?
Euro cables are the most pants on head I see depending on the battery system I work on. For a place with higher regulation, skipping color coding is an odd choice.
@sneaky_krait7271 Generally it feels like they specced everything to run at 100% rated capacity with no or minimal room for error. Exceed the rating by 2%? Catastrophic failure requiring replacement. Square D can handle obscene levels of excursionary abuse and only require the breaker itself to be replaced. (Siemens will melt the bussbars and smoke the main.)
@Warp2090 The house I grew up in and will eventually inherit has a signed date of 1967 in the 200A Square-D panel (Originally Electric baseboards swapped to Gas hot-water baseboards in the 80s.) And honestly I think it's God's gift to men... Planning to swap back to Electric hot water and dryer plus minisplits once I legally inherit the property... I cannot stress enough how well designed Square-D stuff (at least prior to 9/11) is. Practically bulletproof and affordable.
Yes! Another upload from my new favorite youtuber! Love the humor, sarcasm , and lessons about life and machinery, with some work as a bonus!
Yes. Pure gold
My dream come true! An electrician that has the humor and common sense of AvE and the trade of the Duclau!

New to industrial electrician and you videos help me out and theyre fun to watch

Not sure i really understand wtf I'm watching, but given the sarcasm and no bullshit no frills approach, I'll learn something
Learn there are more fun places to be an electrician at than a poop factory.
Goddamn. I suddenly found this channel, and I love it from the first time.
Keep up the good work and greetings from Europe. :)

was thrilled to see you posted again!
Oh I like this channel!!!! Let's see some more goodies. I need more control in my life
So that's what Aussies talk about when things are meggered!
Your narration style is like @fishingarrett (quite fun)
Clogged pump = "obviously an electrical problem". If the motor rotation was locked, I would expect the drive to trip on overload.
Just found your channel. Subscribed!
Keep it up love the content

Yea, i share the same sentiment towards heatshrink. If it isn't needed for strain relief or liquid protection, it doesn't go on.
Great channel. Glad I stumbled in.

Keep those vids, coming.
I’ll watch, comment and like them!
Nice crimper also cool meter and meg
You gotta love VFD's
Count your blessings, Could have been an Altivar.
Oh boi!! Where did you get that Megger? An antique shop?
The G120X would be so much nicer if it wasn't gimped from showing up in Startdrive.
Enjoy the videos, keep them comi9ng...
Big Clive fan, huh?
Do you check inductance on the phases too or is it too hard to find the right values for whatever you're working on that day?
What clamp meter is that? I really want the detachable screen.
Fluke 381 is one of them
They called you out because the pump clogged lmafo
Not 100% sure this is European color coating, or its extremely dirty?
Here in Europe we have brown,black,gray as the phases and usually for 3 phase in that order to get a right turning field.
Older cables mostly have a second black instead of gray.

Guys pretty whitty. Always the elechivken with the jokes.
awesome

The larger the hp of a motor the less resistance between phases in my experience
6:23 I have my wife for that. Crimps EVERYTHING.😭
anyu chance to see a teardown and full signal path for one of thse huge vfds?, do they all use igbts even the old ones?
I would have checked the pump first. I bet it was clogged with wet wipes.
What VFD brands do you recommend?
Yaskawa

Theoretically yes. In practice, it would require a millwright to think, and that's not what they're paid for.
I’ve learned that a lot of guys are quick to blame the thing they understand the least

Siemens is garbage. You need a better boss. =3
Why is it garbage?

@@NoPegs my house has some square D breakers from the 60's made in Detroit. They are still 100% functional and in great shape..

You need to tell most European paper mills that their Siemens drives ranging from 0.1 kW to 1 MW are bad. Never seen a faulty one.
hahaha farts
0.0 PPE
Uninsulated tools on a 3 phase line!!! Fluke users sure are a "special" bunch
If you know it's dead, insulated tools are irrelevant.
@aboreddev never assume it's dead!
@@Steel-l4wkeyword there was know not assume
you really made the video uninteresting!
