Electrical Substation Tour

Harris provided construction management services for an electrical substation project in the Silicon Valley. In this video, Harris Project Manager Rocco Colicchia gives a tour of the substation and discusses the services Harris provided. The project reached completion in March and the municipal utility's crews successfully connected the new substation to the 60kV line.

Better than 90% of videos out there on related subjects. I will use this in my pre-apprenticeship class, thank you.

[@joshuawagner2590]

Thank you for this video. I'm a writer conducting research on electrical substations and this video was quite informational. :-)

[@LFTRnow]

If you just want the electrical tour and nothing about the users, skip to 0:42 or so. You can also stop at 2:30 if you want.

[@garag3054]

Nice video! I’m a fan of and photographer of all things powerpoles and lines. Wish this had been more involved and thus a longer video as I’m trying to add more and varied info about electricity & it’s distribution to my knowledge.

[@TheJMurray703]

Like seeing all the SEL relays!

[@shawncampbell1792]

Yup, I like them a lot too.

[@heathers2706]

Wow that's awesome I love this and wires are incredible close up before connecting. Can you try to not be shocked?

[@vulcancritic]

2:24 super explicit sticker on his helmet had to be blurred out

[@Renville80]

vulcancritic not likely explicit, just a need to protect client confidentiality.

[@Pinky-lg3lz]

I like the first idea better; Leaves more to the imagination.

[@balletopera3401]

Good tour

[@yoshicrafto2242]

Thanks

[@johnclyne6350]

I’m lost on the tour? The tour must have been abbreviated? Did I blink my eye? Where did he say the flux capacitor was? I saw the narrow backs in the switch house-check. Lots of bus work & disconnects-check. Flux capacitor?

[@irfanaslam9683]

Nice Work.

[@runbou3485]

អរគុណThank

[@gangadhardas5622]

Ok.which location

[@Incabrazil]

No Brasil é comum subtransmissao em 88 e 138 kv e distribuição em 13.8 e 34.5 kv

[@DarthMaro]

Nice tour, thanks.

[@BearsTrains]

Unusual voltages. Here it would be 66 to 22kV. Only 1 protection per feeder? I am currently upgrading the firmware in those SEL421s

[@shawncampbell1792]

You mean no backup relays? I noticed that as well. They might still exist but be in remote cabinets too to keep them separated from the gear.

[@McNamEvan]

The relays are multifunction protection. Its likely just the Mains have redundant relays.

[@virus1x]

I think they are only talking L voltage not Primary.

Very cool and nice video

[@audomaroregalado9457]

great overview about, thanks

[@_haringjuan]

Is there any health risk living near of the substation? Thanks

[@samschannel531]

Besides breaking in and being turned into an over cooked chicken strip when you contact one of the buses, nope.

[@chadharmon7563]

That was a tour?

[@JWSU]

How long does it take to learn all of the components in the substation?

[@faithfultheology]

Jesuswillsaveus 3 minutes on youtube

[@GTI18tvw]

The circuit breakers look like 145KV breakers but the is bus 72.5KV

[@ihatnecksered]

I thought it looked odd too. In the UK distribution we generally run 132kV down to 33kV and the insulator sizes are very similar to those.

[@BearsTrains]

Same here in Australia

[@shawncampbell1792]

They might have designed the station for higher BIL for future conversion to a higher voltage. Or just designed with higher BIL as an insurance policy.

[@GTI18tvw]

more than likely a 69kv/12.47kv sub.

[@shawncampbell1792]

If its in California I think they use 66kV out there not 69kV like where I'm in the midwest. Also their 12kV is typically exactly that - 12000V nominal. Different voltage systems out there than in the midwest. California distribution started out mainly as delta so transfomrers were wound for 12000V. Over time, utilities like SCE have been changing over to WYE systems so you have 12000Y/6930V. Here in the midwest we used to have 7200V delta systems and then they were upconverted to wye systems, thus came 12,470Y/7200V. Existing transformer units were changed to be wye connected instead of delta.

[@trueogkilla]

69-13

[@Renville80]

cybhunter007 one of the benefits of wye distribution is that you only need to run one hot wire into residential areas (along with the neutral of course) while all delta systems consist of two or three hot wires on the primary distribution lines.

SEL 2411, was awesome!

[@Nonaddictive]

you can start by keeping your hand down bud

[@Engineer9736]

NateZermeno you can start by keeping your respectless mouth closed bud

[@orange70383]

HVDC will eventually replace long distance AC power transmission.

[@aamirawan7998]

How will you step down the HV DC? Transformers cannot work with DC power

[@LFTRnow]

@@aamirawan7998 You are almost correct. A regular AC transformer can't do it. You need what basically amounts to a switching power supply. I found a lot of info on this on Wikipedia: en.wikipedia.org/wiki/High-voltage_direct_current

[@legominimovieproductions]

maybe one day, but the amount of extra switching tech that is requiered is not effecient for those small substations, so they would stay ac forever and only the real "high-voltage" lines at hundrets of KV would be dc

[@JWSU]

I'm interested

[@deustitties3589]

Look, buddy, I'm an engineer that means I solve problems

[@corydodge2881]

Lol engineers crack me up, all that book knowledge and no common sense.

[@sauravmazumdar5369]

good...

[@virus1x]

60 kv? I think he means 138kv lol

[@ExeDist]

Corny music, but nice video
