Substations: Basic Principles | Circuit Breakers | Disconnectors | Relays | CTs & VTs | Arresters

A quick look into the main assets inside an electrical substation, including the Voltage Transformers (VTs) and Current Transformers (CTs), Disconnectors, Circuit Breakers, Relays and Transformers. Let's see how they work individually and as a team to perform the necessary functions of the substation.

Substations are key to the operation of the power system. A new video on power system protection is coming soon....

What assets would you like to see in Part 2 of this video? 🤔

Perfect description of my last 30 years at work on maintenance and repair of subs. Thanks.

Thank you for these great presentations. I am new to relays and learning from guys who've been here for many years. I hear their words but have no idea what that piece of equipment looks like. I look at substation prints, and it all a foreign language. Your videos are a very necessary visual for me. You have really helped me put the pieces of the puzzle together. Thank you.

Outstanding presentation of an electric substation.

This stuff is so far over my head. Its more amazing than any other field, from vehicles to buildings. It's crazy how differently God made us, how, for some people, this comes naturally and they're super intrigued by it.

I tip my non existent hat to all of you gentlemen that keep our lives lit up, cool and warm. 💙💙

Very nice illustration of an Outdoor substation and its equipments. Would appreciate a video on Protection schemes and Busbar arrangement schemes.
Thanks!

Just applied for a position as a substation technician (currently a network maintenance technician at a pretty prominent network company in boston mass) the operations, and mechanics within a substation intrigues me so much and I'm really hoping i land this loved this detailed video...comments here are awesome as well

[bloodynaura]

Good explanation, simple and to the point. Doesn't try to over complicate it.

[MoussaKHALFI-ztkr]

Amazing explanation, highly recommanded!

[iceboy]

Awesome Video! We call it a Ground Grid here in the US.

[hamradiojim]

Well now, that was exciting! Thanks!

[jacobjohn]

VERY HELPFUL AND THANK YOU FOR DESCRIPTION

[michaelma]

Thanks for the explanation.. very clear and great visual

[briannsama]

Thank you for your tutorial, am learning.

[afghaneuropeanfoods]

very very nice and easy to understand, thanks

[maksim_belostozky]

Спасибо большое! Изучаю вместе с вами английский язык!)

[fabianmaphane]

i really enjoyed watching your video..great explanation..thanks

[GeorgeAlbercook]

Great explanation! I was hoping that you were going to explain reclosers. I would like to understand how the old oil filled mechanical ones could "count" the number of re-close attempts and vary the time all without stable power.

Excellent introductory video.
Any chance of a video about substation shunt-reactors?
Probably too niche, but no harm in asking.

[claudioerra]

Very interesting and well done. Thank you. I am an Italian teacher and I would like to publish the same video on my YT channel but with an Italian voice speaking for my students. Can I? Of course I would mention your channel in the video description. Please let me know.
