ok👍👍

This is not correct

New to the transformer industry but trying to learn everything I can. From what I understand, the hum is both from the core (laminations) and the coil windings, but is primarily from the laminations expanding and contracting with each AC phase cycle via a process called magnetostriction.

hi sir my name Abdullah Rashid I am from Pakistan and I'm 19 years old I have 3 to 4 years experience in eclectic motor winding and electrician I have been involved in this field since I was 14 years old. I am passionate about electrical work.

good one for transformer experienced engineers

No explanation at all.

A very informative video. Thanks 👍

Nice

Back to source.. 😊not earth

Rong rong... current of unbalenced network return from loads towards exactely to the coil of transformer that generat it

It was a good video explanation about the transformer was very good

So is there a way to fix a leaking cooling fin manifolds?

Guys anyone can explain does ht generator or transformer need to connect ngr

You sould not install crystal IR windows in any swichtgear They do not have a lifetime warranty. -More expensive -they do not withstand impacts and turn black over time (no security) -they have a difference of 87% of the real temperature that they are taking with the camera. -It does not have a good inspection angle.

"First of all it's important to know that the neutral is the return path for current in the system" - Yes agree. Then... "That current is looking for the least resistance path, back to earth" - What?????

"it allows that fault current to travel back to the earth". WYM "back to the earth"? The earth generating the current now?

Please make the distinction between “earth ground” vs “equipment ground”. These are two very different things that people often get confused. The neutral is the return path for current under NORMAL operation. However, during a ground fault (a phase hits the metal casing of its motor for example) the neutral DOES NOT CARRY CURRENT INTO THE EARTH. Now, I say none but in reality about .000001% might. The equipment grounding conductor (this will be a green, green/yellow or in residential bare wire) will carry current BACK TO THE SOURCE. In a newly derived system, like the video above, the secondary side of the transformer(we can assume this is going to a factory or feeding distribution lines since it has a neutral (wye transformer)) will have the neutral and equipment grounding conductor bonded. So yes the neutral and equipment bonding conductor are very similar in where they go, but serve different purposes. However, let’s this about this, EARTH GROUND. Yes the neutral and equipment grounding conductor will be bonded and EARTH GROUNDED, meaning a freaking rod (or many rods in the case of a substation) will be driven into the earth. That is earth ground. Earth ground doesn’t mean JACK for fault current. The resistance path back to source is very very low, the resistance path into the ground (relatively) is very high. No freaking fault current goes into the ground. Stop the lies.

Nice video

Hi

Very well explained. Hope you can have more videos. Thanks

Absolutely no current will go to ground. Only in system faults. Current will return to its generative source.

Good info!

Very informative. Thank you.

Good Information!

Reach out to SWE for all your motor needs!

Informative!

Good job Dean!

Informative!

Interesting

Interesting!

Good to know

Very informative!

Hi sir! What kind of chrom do you use? Perkin Elmer?

Hi sir! Where is your company located? I’m very experienced chemistry on oil transformers and I would like to ask some questions. Regards

Winding temperature device is indeed important. It displays the temperature compensated by load. This is typically the relay that cooling fans are controlled by. If temperatures exceed a predetermined level, the winding temp device will alarm and then trip the circuit breaker, clearing the transformer.

Transformers, robots in disguise.🙂

Great information, thank you for taking the time to create this video! 👍👍

As a courtesy when I did substation vegetation spraying if I noted anything visually abnormal I would note what piece of equipment it was and where it was located in the sub. So that way \when I called dispatch to log me out of the sub I could let them know.

Weak volume

I enjoyed this video sweet and very helpful 😊

Not to mention, the window is not made of glass. Glass does not pass IR wavelengths and the IR windows are made of a few different chemical (polymer) or crystal compositions.

This is very interesting and educational to the public, but there is one minor flaw that affects the quality of the video: audio quality. Part of this could be drastically improved by using a wireless lapelle mic instead of the camcorder's built-in mic. The camcorder mic picks up wind noise and also outside noises from equipment being used in the nearby neighborhood. Also when Mr. Stone turns away from the camera while using the built-in mic, the clarity of his voice is affected. If there's a concern about interference with a wireless mic, you can always combine silent video footage with separately recorded narration after the fact.

You guys hiring?

awesome video. thank you, sir.

Thanks for sharing info.

Nice video, thanks :)

Good sir

Please make a video of motor maintainance,testing

I saw a valve in the bottom of the radiator, what happen if someone open it by accident and leave it open for a weekend?
