Overcurrent Protection in Electrical Substations: the simple genius of the Relay

[@VisualElectric_]

Should I do a video on other protection schemes? Distance or Unit protection? 🤔

[@KilisonofDis]

Yes, both please!

[@shivajighere5517]

Best learning video

[@MohammedAlFakhroo]

Absolutely! Your explanation is perfect.

[@seeingnature9422]

Yes

[@enriqueantoniogomez1692]

Yes, distance protection please. That was an excellent explanation

[@arishsiddiqui3292]

What an absolutely brilliant visualization. I am blown away. Can't believe I didn't know if this channel before.

Very basic relay protection in electrical substations. Not only feeder protection but usually motors or some cases generators, transformers. The overcurrent relays I worked on were manufactured by General Electric model IAC or Westinghouse model CO. We would generally set the current tap, followed by the time dial. Once set, we would "bench test" and check the minimum pickup current first. Then check the operating time it would take to close the main contacts. Final test would be a functional target test which was the relay's visual target indicating which phase tripped the circuit where the fault occurred. Upon completion of tests, returned relay to service. Very good video on the overcurrent relay concept.

the animation helps a lot, much easier to understand this way.

[@VictorAlvarezmx]

Excellent content, very clear and professional. Thanks for sharing this knowledge and your hard work making it.

[@introvertedsinethemba]

Agree♥️

[@lyaeusv3828]

Finally I get to look at how the mechanism works ! Great video

[@Adhithya2003]

The best video, it clears a lot of doubt, I am now currently taking protection and switchgear course, No book/video has connected the dots as much as your video. Thank you.

[@VisualElectric_]

Glad it was helpful!

[@VisualElectric_]

Thank you for the kind comments.

[@wilsonmateus301]

Thank you so much, with the industry growing in the UK this is much needed, perfect video

[@wilsonmateus301]

Where can we get more videos like this?

[@mahermokhtar]

a very clear introduction to the overcurrent protection, thank you

[@danielpesta]

Great explanation and fabulous animation.

[@jordd6206]

Been binging this channels videos, all very good

[@DeaconBlues97]

Your video is amazing man, the animations along with the explanation are so well done and you can easily understand everything! Thank you so much, I hadn't seen content like yours here in yt, very technical and very well done at the same time! New subscriber!

[@jairammangluru3232]

Very well explained and professionally crafted video. One of the best technical videos i have watched on youtube. Very simple and to the point. Wonderfull Sir. Thanks for your hardwork. Appreciated. Keep it up 👍👍. Am Subscribed to your channel. From India.

[@libervolucion]

This video has been both interesting and very helpful. Thank you.

[@JohnDop]

Excellent video! Very clear and easy to understand. Thank you

[@baylisskid]

Really simple videos. Thanks. I am very visual and this has helped a great deal.

[@jitughori3119]

What a thorough explanation 👌👍

[@mernok2001]

Some medium voltage circuit breakers have bult-in( integrated) relays. This eliminates the need of several meters of cable from the current transformer to the relay room and back to the circuit breaker.If that cable is damaged there is no protection.

[@billylun9634]

Thankyou very much for your time and dedication in providing this helpful video❤🙏

[@shavaizkhan8165]

Excellent Presentation ! Thanks for the video

[@BasicElectricalKnowledge]

Sir u are a blessing ❤❤❤

[@srijonbordoloi6948]

best explanation and best animations

[@randomthing3785]

What software do you use for making this visualization?

[@VisualElectric_]

Mostly Blender.

[@adityayadav6712]

Ultimate Explanation....Love You

[@RaheelSyed]

Brilliant work! thank you so much!

[@IreneKoryoeTetteh]

This is amazing God bless you Thank you ❤

[@tneseidovv5493]

Why the hell this video explains such things way better that my university teacher...

[@dkpelect]

Great content. Thanks for the efforts.

[@oshovision-lx1jw]

Sir very good explanation. Make videos on 87T,

[@onesmushangula3116]

Thank you so much. The content at colleges sometimes need update.

[@khadijahussain1938]

Thanks for your insight, can you make a video measuring high voltage like 2k-5k AVC and what equipment/devises use in this process or measuring, Thank you

[@williamrobarge3111]

Excellent job

[@surendrakverma555]

Very good. Thanks 🙏

[@Sudharshan9834]

Please make videos more like this

[@sureshsaha9701]

Dear Colleagues, Its the discrimination❤ of the relay within the substation that affects the sudden change in blood pressure of a human if Again you are going to use or apply the ANN or AN system or ART system into a human being which is very dangerous to do or to follow a system or an art that will affects the life of the people. A reason i try to ignore it and really need to stop for it is not an ART anymore if everyone of us are all in trouble just because of the change in current reading or whatever the rate of value within a relay called discrimination. It should not be applied to a human being. Discrimination wise, everyone of us has the right or freedom to choose whatever they wanted, without harm or risk of life to the people or to any individual. In general, the AN or ART system should not be applied to a human or to a life of any individual. There are some advantages can be use which are good like the corrections of our face or any part of are body can called good because its not risky or dangerous but those ways or methods that are dissadvantages called bad or wrong like the discrimination within a relay its wrong, how would you like being cut everytime they slice a beef or brisket? its dangerous to think off and its to barbaric or a cannivalism to think if applied to a human as an art or an. Again, as my mentor told me, it should be the good only to use or to do as an advantage or useful to a human life. Life is precious! it should be protected and Treasured Forever. Thank you very much i hope youll never get offended on my message because am messing up and my heart or blood pressure is under discrimanation the whole night. tThank you for your understanding that my heart or our hearts should be free to anyone to feel happy and comfortable to breath freely adequately. With Respect, Tomas O. Yabut P.S. Doc, please move out the discrimination in my heart and those unecessary add ons medications and finding within my health. I need to be strong and healthy again, as your gift for us a lifetime. Thanks again .❤

[@jask320]

Wow

[@Red_Light_andBlue]

Ah, yes. I love discrimination.
