@@the_townleys working on substations is a part of a general electricians scope? im curious because up in canada we have electricians, linesmen, power system techs, instrumentation techs. so I wasnt sure what scope it would fall under.
Hi good morning. There are those that build the buildings.thats a wireman electrician. Then there are those that energize the building itself.those are LINEMAN. Then you have those that ensure those lines stay energized.thats a Substation Electrician. A Substation Electrician maintains all the components inside the Substation so the lines stay energized. The only way to make it safe is to turn it off.😁
In order to maintain a piece of equipment inside the sub most of the time that piece of equipment needs to be taken out of service. If it's a Transformer that needs to be maintained they will take that Transformer out of service install a mobile substation in some cases just to keep the power on for the public
@@the_townleys thats what i figured, probably going to be my second ticket. here in canada linesman deal with everything from the primary transmission to the primary side of the step down transformer. Got to work around a substation doing a backup generator for it. Got me more interested in taking substation tech as my second ticket in 4-5 years.
Really like how you explain the parts names and what they do! Such as corona ring. More videos please. Would be interesting to see you explain reactor banks and capacitors.
Always awesome to see the products that I build every day in use! Seeing how the cap bank works with the rest of the substation is really cool! Thanks for this video.
As a transmission system operator currently in training these videos are awesome. Due to covid they arent letting me into the field. Surge impedance loading (SIL) is the concept of when and why transmission lines will act either capacitive or reactive. During light loading, the lines will produce MVars, and during high loading they consume MVars. Managing system voltage using capacitor banks and reactor banks is something we do constantly in my control room.
Good work. Don't be distracted by production values - it's what's coming from yer brain that matters and the content is focused and relevant to each episode. Disclaimer, I've only watched 3. So far.
Have been in the commercial electrical/electronics field for over 50 years and have always had an interest in high voltage transmission lines and substations, but have never worked on them. Your videos are fantastic in instruction and understanding their workings. I have often seen the rings (corona rings) on high voltage lines and now I know there purpose. When I was a teenage there were high voltage towers that ran over a large reservoir near our house. You could hear and see the corona discharge on humid summer nights, very strange to hear and watch. Keep sharing and Thanks.
Watched all 3 of your videos. Excellent for sure. The information you presented is simple enough for most folks and you didn’t launch into formulas and technospeak. I appreciate it. Thanks.
Thank you a lot for putting out these great videos, I just found your channel recently and I thoroughly enjoy watching and learning from you. I work as an electronics engineer in MEMS (micro-electro-motoric-systems) development, so this is the polar opposite end of the spectrum of what electrical engineering is used for..
Thank you for putting together this video. I'm totally fascinated by infrastructure--and am an infrastructure tourist. When I was 5, I lived in New Jersey. My parents gave me a book on New York City infrastructure... and begged my parents to take me to the places listed in the book. Decades later, I'm still fascinated by infrastructure and am still an infrastructure tourist. This is exactly the sort of video I love, the sort I watch time and time again.
I’m glad guys like you share your knowledge and experience. I’ve learned so much over the years just watching TH-cam videos like yours. Thanks for sharing
Thanks for the video. One the reasons you want to ground the capacitors is dielectric hystersis. Charge will reappear due charge stored in the dielectric.
I've worked on a few windfarms in the Midwest and up in Maine on the comms side so I spend all of my time in the control house and O&M buildings but I was always curious about how each component in the substation works together. Your videos have answered those questions ive had. Thank you!!!
This is awesome... subscribed! These places look terrifying to a newbie but the more you know the more you see how well engineered protection and safety is.
You’re right, substation protection is very well engineered, but it’s engineered by humans. I’m sure our guy here can tell you about all the engineering errors caught in the commissioning phase. “Trust, but verify” is the motto here.
i'm a software engineer and i absolutely love interlock systems. i typically design the systems i build opposite most people - i put a lot of trips in them so that if conditions are outside of the expected parameters they fail. it's more difficult to build up front, but i think the payoff is well worth it when something goes wrong and rather than continuing to run it shuts off.
Same here. I've written online transaction processing systems, material handling systems and robotics. I thought that last mechanical interlock was truly beautiful, so simple, so elegant and effective. It's easy to design something that's needlessly complex; it's difficult to design something (that hasn't been designed before) that is simple and elegant.
Thank you, this is very interesting. You hear a lot of bad stuff about US power grid, but this site looks like it's very very well engineered and maintained. Subscribed!
Your HV / substation video's are great. Nice pace, nice level of detail, very genuine. Thanks for taking the time to do it, they're very interesting. Keep them coming!
I take it that your substation was still under construction (de-energized) while you were demonstrating the capacitor bank kirk interlock. I personally tested a new capacitor bank (start to finish) for a 115Kv substation. Provided about 43 megavars to the system.
That was really interesting to watch, even though I'm not connected with electrical work in any way (if you'll pardon the pun). I always wondered what those rings were for and now I know. Great video.
Great video! I wish I had these when I was taking my NICET exams. I did primarily data center work, substations were scary black boxes to me. Keep up the good work!
Finally, someone give me a name for those corona ring ! Thank you so much ! One question: when you walk under the high voltage powered lines, do you wear a protective outfit ? Do you feel and are you exposed to a dangerous electrical field ?
No protection. Since the voltage is around us, and not going through us, there is no danger. The crazy amount of substation grounding and rock protect us. If there was 0 grounding and 0 rock and I was grabbing onto a ground rod near the conductors, i would get the crap shocked out of me. These are designed so there is 0 risk. I only feel it if im close to a low conductor and i touch a piece of grounded metal, i get a shock equivalent to a balloon.
Submarine line terminals also have some neat interlocks going on. They supply power for the repeaters/amplifiers at the bottom of the ocean, can be thousands of volts (DC IIRC), so you don't want to be sticking your hands into something that could burn them off. There's usually a sequence of operations that must be performed in order to release keys that then allow the next set of operations to be performed, eventually leading to a safe system to work on Sometimes there's even operations that require two keys to be turned, so you need a second person and they are spaced far enough apart that one person cannot physically do it themselves.
Hey @SpeedFreakLS1. I believe the rings on the arrestors that are underhung on the deadend structure you called corona rings are actually Grading rings to ensure a uniform voltage across the arrestors. A lot of people call those corona rings but typically when they are on an arrestor their function is typically to act as a grading ring. Keep up the great videos though, there are a few people in our office that are really enjoying them!!!!
You are correct. Its technically both on that specific Hubbell arrestor. The ring around the hardware is the corona ring. The ring around the insulator is the grading ring. 1 piece with 2 functions!
Very interesting. Some good engineering there. When you say primitive on the interlocks, I think maybe that is a good thing. You can at least see how it works not so much with software. Near where I live there is a transition from overhead cables on towers to underground cables. I think it is 132kv and it is quite loud more so when it has been raining. Nice video look forward to the next one :)
I know I'm late, but what about the loose pipe clamp at 10:40 second clamp down on the right. With it being part of an interlock I would think tight would be better.
I wouldn't call mechanical interlocks as _"primitive",_ but rather a worthwhile and necessary feature based on human fallibility. Idiot proofing is always advantageous. Thanks for sharing. 😉👌🏼
Hey you are awesome! I hope these are fetched for teaching in the University, instead of boring presentations; complementary at least. Isn't scary to you that sound being so close?
sometimes capacitor banks have timed kirk keys that have a mechanical timing actuator before it releases the key, so you dont just ground the capacitor straight away.
The corona shielding is interesting. Does the corona effect cause much in the way of RF interference with the instrumentation? Edit: I love a physical interlock, primitive or otherwise. I trust them over a software interlock any day.
I can't find any info on this, but I've been curious: Why are some wires run in pairs for (what I assume is) the same voltage & phase (Say at 16:20, to the right of the poles)? I'm thinking something with surface area, but I'm very unsure about it...
@9:42 Am I correct in thinking that the interlock arm is secured to the shaft by the friction of the clamp?? I have seen clamps loose their original tension over time and in this case I wonder if this has been considered. This would apply to the breaker interlock on the opposite shaft.
yes, but we have piercing bolts as well (not installed when I filmed). Those piercing bolts eliminate any slipping if bolts go loose. Great observation thought!
I know Aluminum is cheap , just thinking that for the AAC you could go ACC, (copper), and get some better longevity out of the conduit expansion joints, or Did I miss something ....??
I have often noticed the sizzling, but had never heard about the Corona shields on sharp edges and bolts before, I find that fascinating. When I hear an extra noisy pole, I just always assumed it was tracking over the insulator or something, but I guess it could just mean it has a sharp edge. What's the minimum voltage that this is an issue with?
Any suggestions? A few months ago a new remotely controlled pole top switch was installed on the next street. It's on a 34.5Kv primary. Ever since then AM radio reception in this area is nothing but static. I called the power company to no avail. Even when I drive my car under that line the radio reception is blocked. What can I do to get that problem corrected? Thanks.
nothing yet. MFG is coming out to take an oil sample since the DGA analyzer i talked about in this video is not yet hooked up in the other transformer yet. ill do a video after its all fixed. could be days or months.
Really cool mechanical interlock, do you know who makes it? Was that the switch manufacture or someone else? Much better then Kirk Keys for an instance like that, basically fool proof. Clean looking yard and control room. Enjoying the videos, makes me really miss substation work. Work safe.
At the dead end, you walked under the cables that sounds “life” isn’t that dangerous towalk under there. You hear scary things of people in substations. Btw aaaa that hum in de background lovely.
As a suggestion, when pointing out specific items in your vids try pointing with finger, pencil or pen to the item on the screen. Might help us non-elects with the info.
You can see the surge arresters mounted on top of the transformers - they are the thin insulators with the large hoola hoop shaped things at the top. They are there to protect the transformers for lightning.

Why are dry core reactors so common in the US? Here they are almost always the oil filled ones that look like a transformer. They are also usually variable.

Grate input of info ,corona is not good causes corrosion, thanx for vid very interesting
I am really enjoying this series - is there any device you can use to see the corona (except total darkness I suppose)
Look up COROcam
Uv sensitive camera with narrow band filters
sometimes capacitor banks have timed kirk keys that have a mechanical timing actuator before it releases the key, so you dont just ground the capacitor straight away.

What's the minimum voltage that this is an issue with?
Typically anything 230kV and over gets the hardware and corona shields, but its all based on the engineering company.
The 3rd interlock is like the lineman's version of an escape room
If the corona thing is so close to you would it be possible for it to jump an arc through your camera and bad things happen?
Gret Video. Was curious is that nitrogen tank next to the transformer? Seen these transformer look like they have a conservator tank.

Great vid! What happened to your other vids of the transformers? (The walk-around, nameplate explanation, and the start up vids)
One of the substation owners politely asked me to remove due to some security concerns.
heck i'd love to see a 345KV arc sometime. I know it's not good for the sub though, just cool to look at : )
You just reminded I had another video of one. I'll release it shortly. th-cam.com/video/7SKV2bGkq24/w-d-xo.html

I love this type of info. Get a ded cat for your mic!
Have you ever heard of power line RFI causing interference on microwave bands?
Does the substation have any kind of lightening protection?
Always.
whatever lightning does to something when it strikes it,it does what it does and u fix it😁
You can see the surge arresters mounted on top of the transformers - they are the thin insulators with the large hoola hoop shaped things at the top. They are there to protect the transformers for lightning.

Given the high voltage, how much does heavy fog or haevy mist affect things?
Informative
hey Speed, kinda off topic, but, what are those huge cylindrical things @ 4:19 in the back view there, just off the right side of the building. also right behind the capacitor bank @ 5:32.

and i hear A LOT of coronal discharging, and you also explained the possible reason why lol, sorry.
shame me for making a mid-video post :P
yeah, i eventually reached the part of the shunt reactors and the corona reasons.....
Are those "reactors" just regular induction coils or do they have some other magic shit going on?
Is it possible to have an automatic transfer switch with 3 power inputs?
Of course!
5:00 and how often this unit itself needs to be sent for calibration?
Great question! I'm not sure. Honestly I doubt zero calibration unless a problem pops up. Not saying that's right, just staying that's what I believe
Why are dry core reactors so common in the US? Here they are almost always the oil filled ones that look like a transformer. They are also usually variable.
Great Question! I believe its cost. Most of them are not made in the US so they must be shipped long distances.
A key - can't go wrong with that because its a physical object you have to physically carry with you.
Can you imagine the result closing the circuit while its still grounded?
What is your job title if you don’t mind me asking
is it 60hz ac from the windfarm?
I’ve worked with SCADA interlocks and Kirk key interlocks. When these systems work as intended they save equipment and lives.
