Identify equipment in a substation (35 - Electricity Distribution)

Let's identify all the key parts of a substation by inspection: transformers, voltage regulators, lightning arresters, reconnectors, fuses, etc. We'll look at a few examples.

Full edX course with interspersed practice problems to help you learn:

Aaron Danner is a professor in the Department of Electrical and Computer Engineering at the National University of Singapore.

Very nice 👍
I think watching disconnector switch arcs has a calming and soothing effect.

[fethilakhdari]

Both excellent and outstanding video, please keep them coming.
Cheers

Thank you for your videos, they are very easy to understand and informational!

[richa]

Great video. Very clear and well presented. Thank you

I have signed up for prof Danner’s courses on edX, very interesting and informative; contrary to usual college level circuit courses loaded with 1st order and 2nd order ODEs, this course is hugely practical with not only oscilloscope graphs bench experiments but also very detailed data sheet explanations on electrical elements used in practice 😅

Thank you very much for this. Perfect.

Great and highly informative videos. Thank you Prof.

[ClaudinneV]

Thanks a lot. Very well explained. Not strange coming from a professor.

[salaheddinerahila]

Perfect and well detailed explanation, thanks!

My brother worked over 40 years for PECO ( now Exelon ). First thing the old guy he was with told him he had to learn is where are the best bars thru out Philly. He never packed a lunch and usually drank mean ate lunch at bars.

Great video. The company that I work for builds the polygonal poles for substations and other electrical transmission applications.

Lightening arrestor. ordinarily open. New information to me. thank you

At the 8:30-8:34 mark on the circuit breaker you called the bushings that point out at an angle buss bars. Was this in fact a buss bar on this specific piece of equipment or was that a mistake? They look like bushings to me and just trying to clarify here in case there was a mistake made

Excellent. Not enough likes in this video.

Nice lesson Aaron Thanks. I am now subscribed👍

[sambathbunkh]

Great video shows, I am also working at grid substation.

Hi Aaron, how much would be the estimated cost to build or construct a high voltage substation? Let's say in a 230kV line.

[TexasEngineer]

There is a reason you cannot eliminate the switch by using just a breaker. In order to work on the transmission line, by applying grounds, there must be a visible open switch to attach the grounds. It is a safety rule. Utility do not like to use a switch to open a circuit because it stresses the switch jaws and sometimes goes very bad. This equipment is not cheap. Some breakers are oil breakers and the newer ones are SF6. The old oil breakers are large and heavy. Also oil breakers have a potential of an oil spill.

Nice presentation and information. Question: Are "Ground Switches" considered "Fuse Switches"? Thanks.
