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.
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.
You are correct, provided the alarm is properly working. I would suggest that you have this circuit tested and confirm everything is working correctly. If you should have any further questions, please feel free to email me at ron.nicholas@swelectric.com
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.
The majority of the oil would drain out of the transformer. The radiators have valves where they are mounted to the transformer. Shutting off these valves allows you to isolate a bank of radiators and drain just the oil in those radiators, so if you need to replace or repair one bank of radiators you don't need to drain the whole transformer. The valves you are asking about are to drain the radiator tubes.
Any valve SHOULD also have a cap or plug after it. So if the valve were to be accidentally, vibrated or purposefully opened the cap or plug would prevent the loss of fluid. Anyone qualified to do maintenance on a transformer would not leave a valve open. At the bottom of a transformer with 10 feet of head pressure and 1 PSI of nitrogen on top there is a lot of pressure that comes out that valve and aside from draining a radiator with it isolated there would be no reason to leave that valve opened.
You all must not have a problem with wildlife. Here in Tn. we use a heat shrink cover up material, everything load side of breaker. Or should I say THEY do, I'm retired as of 2020.
Hey, Thanks for making sure we have power. I'm 45 and I've been preparing for a few years now I can feel day 1 on the sub crew is on its way. The first friend I ever had went on to run sub maintenance here at nv energy.about 210 subs we will be maintaining. I made some mistake up til now. Learning all I can Getting super healthy Just so lucky i saw it.
@@SouthwestElectricCo I worked at the utility co. here in Knoxville. They started covering up years ago and have years more to go. I mostly bent new ridgid conduit when we changed out the old breakers to vacuum breakers while the others did the cover up. We pulled new control wire but relay and test dept. always hooked them up. We were the bulls and they were the brains...lol
@@AmericanOne9621 I'm a retired testman. I had the pleasure to work with some very skillfull electricians. All of our electricians installed all the conduit, cable, breakers, transformers, relays, etc. My job was to ensure that the wiring was installed as per the schematic diagrams or "3" line diagrams. Also was responsible for functional testing and commissioning. God Bless our substation Electricians!
good one for transformer experienced engineers
Very well explained. Hope you can have more videos. Thanks
A very informative video. Thanks 👍

Thank you for taking the time to watch our video! We are just getting started with our video production here, and we appreciate the advice.

awesome video. thank you, sir.
Glad you liked it!
It was a good video explanation about the transformer was very good
Thank you for watching our video! We are happy to hear that you enjoyed it and found it educational!

Great work! Thank you for sharing.
I enjoyed this video sweet and very helpful 😊
Glad it was helpful!
Very informative. Thank you.
Very informative!
Informative!
So is there a way to fix a leaking cooling fin manifolds?
This ultimately depends on where the leak is located and the type of radiator!
Please make a video of motor maintainance,testing
Thank you for the suggestion!
Thanks for sharing info.
Our pleasure!
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?

Good sir
Nice video, thanks :)
Glad you liked it!
Humming sound of the transformer is causing disturbance in listening. If possible please select any isolated transformer.
Our apologies for the poor sound quality - we suggest watching this one with captions on!
@@SouthwestElectricCo Thanks a lot for your reply. Regards.

We do a lot of work in TN (where this video was shot). It's unfortunately common to find wildlife - always a danger!

You guys hiring?
We are always hiring! You can find our open positions and upload your resume at swelectric.com/careers.
Weak volume
We did have a lot of background noise on this video. Thank you for watching, anyway!
