Circuit Breaker Testing

Circuit breakers allow the flow of energy to be controlled by safely switching currents on and off at all voltage levels of the energy grid. The interrupter and the mechanical drive are the main components that are subject to wear and aging. In order to ensure the proper operation of a circuit breaker throughout its lifetime, diagnostic tests are performed, such as resistance, timing, minimum pick-up, travel, and power factor.

[@bbbildhuu]

Thanks im gonna go test the breakers on my street now

[@SovietRusalka]

I don't know why this was in my recommendations but it was interesting

[@CentralNintendo1]

Same

[@poiuytrewq4645]

SovietRusalka exact same

[@AsitSinha]

same bro

@SovietRusalka Google determined you should become a lineman. They're going to keep gaslighting you until you comply. 😉

[@nuismai]

Same here

[@flaplaya]

Amazing. I wasn't aware that there are multiple contact surfaces in one of these breakers. The arcing contact is sacrificial and the other contacts carry the bulk of the load. Ingenious!

[@F-Man]

My electrical know-how pretty much stops at dealing with household 120v and 240v wiring, but this was ridiculously informative anyway!

[@assassinlexx1993]

Thank you for making sure our aging electrical grid is up to the task. Keeping the lights on. May the safe rules never be broken. Safety is essential for everyone.

[@MrSPACE-hy5ue]

that's more clear than they teach us in university.

[@AntimatePcCustom]

that's because it's theoretical teaching at the university. not practical. but you need the theory before practical learning.

[@lmsubman243]

An instructor told me: "if you learn one breaker you can work eM aLL!" The only thing that changes is the BoX they came in! He was right. They all com in a box!

[@LaneLarson]

The sound of those breakers tripping is one of my favorites.

[@patrickcannell2258]

The old minimum oil Sprecher and Schu. As far as I am concerned the best and most reliable HV and EHV breaker ever made. These things are 40 years old. Before SF6.

[@edwardmcewen]

Excellent video! This was extremely thorough and still easy to follow.

[@simitmishra4981]

Fantastic video and helped practically realize theories learn in books. Keep bring more.

[@MRtucnakCZE]

Gained 5 IQ just by watching this vid.

[@Zerpersande]

Nope. You may be a but smarter but that isn’t the same as intelligence.

[@Klugscheisser2]

THIS is how to make a quality video. Great Job!

[@linuxBlob]

Woo. That was one mighty satisfying video to watch. Informative, direct, and concise.

[@free_spirit1]

How wonderful it is that we live in a time where we can learn about such things so far from one's education or field of expertise. The internet truly is a wonderful thing!

[@DeckardCain1986]

Now I wish I would have studied electric engineering instead of textile engineering

[@namm0x326]

Hey man, it's never too late to change careers...

[@scottpecora371]

As a 56 y/o Psychiatrist I was just having the same thought!

I stayed a while to listen, but you didn't elaborate...

[@klaasklapsigaar1081]

Never too late to change!

[@robertnorthrup1914]

Well done! Much better than most vids on the Tube.

[@thatonethattalksalot7656]

Gotta love those shiny ceramic insulators with their blinging plates!

[@internet146]

Extremely informative. Thanks.

[@CekalaStudios]

Greetings from recommendation land! I stumbled upon this video as it appeared today. So... I decided to have a look, and wow! This is fascinating. Great video! Voiceover is clear, and everything is well-explained. I’m not in the electrical engineering field, however I understood most of the video!

[@movax20h]

Good stuff. Nice testing and measurement tools too, made specifically for a job and analysis of data. The principle is very simple, but the tooling and analysis is what makes it awesome.

[@MsLontje]

valuable information on this video, thank you

[@TheEdisse]

Thank you! Well made video, very easy to follow and understand!

[@justimagine2403]

This is so bad ass! For all the thankless work electrical workers do... Thank You!

[@atenrok]

very thorough and high quality

[@AbdulKareem-gu5gq]

this videos was fantastic . gives the knowledge and helpful to the students and others

[@minnesotaimaging9726]

Amazing level of engineering. I totally wasted 30k on a business degree. These guys are the smart ones.

[@khadijagwen]

This is very interesting. I retired as a Master Electrician in 2003 and had worked on 13.8 kv or less for 32 years. In that Voltage range, at that time, molded case breakers typically had a rating of around a dozen trips before they were rebuilt. We used some motorized breakers for 13.8kv which were around 1 meter cube, all metal, and were made by GE, and I do not know how many trips they could withstand. I avoided these breakers as much as possible.

[@HighestRank]

Khadijah Brown yep testing GE is petty and cruel.

[@TechDEEM]

Great Guide about Circuit Breaker....

[@PrincessHarmonyMoonlight]

Very interesting, I enjoy learning these things :)

[@superbracey]

I don't know how I got here, but I enjoyed it thoroughly.

[@donwatson2741]

Thanks for posting,interesting 👍

[@leswause8937]

Thanks KZbin. I learned something new today. The more you know!

[@Djembe908]

Very educational! Tx

[@Shokkwavez]

I've always wondered about this stuff, very interesting!

[@patrickcannell2258]

That breaker is the old Sprecher and Schuu V head. Was a beaut.

[@patrickcannell2258]

You can say that again. I have been in this industry 35 years post grad. Still my favourite HV and EHV switchgear.

[@ldqbaz]

absolutely fascinating, technology of the everyday, that keeps civilization going, that no one is usually aware of.

[@MusicVidsAT]

It looks the video was made in the switching station Bürs/Vorarlberg.

[@omicronenergy]

Dear MusicVidsAT, you are right, the video was indeed done in Bürs. Very well spotted! Best regards, Your OMICRON-Team

[@jac01055]

Hey, nice vid. What is the equipment shown in 3:02? Is it always a breaker? Thanks

[@omicronenergy]

Hi Jorge, What you see is a North America Substation with so called “Dead Tank” circuit breakers. Typical for such breakers is that they have current transformers mounted on each pole.

[@krisallennavarro8779]

now i knew it!! hahaha thank you

[@subramaniamchandrasekar1397]

What type of insulator material is used to open / close the contact plug and sockets that will withstand say 220 KV and ground?

[@omicronenergy]

Dear Subramaniam Chandrasekar, thank you for you interest in our videos! In high voltage switchgear, today mostly SF6 is used as interrupting medium. It has by far the best arc interruption capabilities for high voltages. In medium voltage, and nowadays even up to 145 kV, vacuum chambers are most common. The real challenge is not withstanding the 220 kV to ground, any insulator will do (often porcelain), the big challenge for circuit breakers is interrupting short circuit currents of magnitudes like 80 kA at high voltage. We hope this answer could clear some things up already. If you have any additional questions, please get in touch with us directly. You can find your local contact person here: www.omicronenergy.com/en/contact/addresses Best Regards, your OMICRON team

[@heroknaderi]

Good to know 😁😎

[@krnlg]

Love this stuff. I need a career change...!

[@Hex-Mas]

Thanks

[@araki916]

Good vid. I was wondering if you'd do a DGA analysis on these types of CB's? Or is that strictly for a XFRM?

[@omicronenergy]

Dear araki916, DGA is not only restricted to power transformers, it is also done on On-Load Tap Changers, Bulk-Oil Circuit Breakers, Oil-Immersed Reactors and so on. Nevertheless, for this type of Circuit Breakers (Minimum Oil Circuit Breakers) DGA is not required, since the oil is utilized as interrupting media and not as an insulation media. Instead of DGA, another measurements are conducted like Oil Dielectric Breakdown and Interfacial Tension among others. Best regards, Your OMICRON team

[@superj1e2z6]

Finally I know what those weird tubes in those substations

[@althuelectronics5158]

[@s.kjainlalitpur2779]

Great Video

[@totaltwit]

A reassuring set of test done here, although, all that exposed mechanics which I would think would lock up in the winter with ice. The internal mechanicals will slow up too, the grease will become hard. These tests need to be done under worst case scenario too.

[@kakilani79]

Good video ...and how much money for this switch .? And the operational life time before maintenance. .

[@omicronenergy]

Kilani Sdudah Dear Mr. Kilan Sdudah, Thank you for your positive statement regarding our video. In your comment you ask about the price of a circuit breaker (switch) and its operational lifetime before maintenance. However, we, OMICRON, are a manufacturer of test equipment and have also a test system called CIBANO 500 with which you can test circuit breakers. We do not manufacture circuit breakers. Therefore, we don’t have price data or maintenance cycle data available. In order to get more information about OMICRON, please visit our website www.omicron.at. If you want to know more about CIBANO 500 please follow the link www.omicron.at/en/products/all/primary-testing-monitoring/cibano-500/ Please just let us know if you need more information. Best regards, Your OMICRON Team

[@shivkumarchouhan6549]

Great job 👍, "Sv "

[@cjgaming5544]

Thanks youtube for recommodation after 7 years

[@vikhyath7496]

How do you measure contact resistance by grounding both incoming and outgoing terminals of the breaker?? Earth resistance will be in parallel in this condition and there will be some error. Correct me if I am wrong. Thank you

[@omicronenergy]

Dear Vikhyath, thanks a lot for your interest to our video and for your comment. Regarding your question: CIBANO 500 offers the new Current Sensor Measurement (CSM) method. This allows the operating times of the circuit breaker to be determined accurately even though the GIS is grounded on both sides. During a close or open operation of the circuit breaker, the current sensor measures the current change through the ground connection or the circuit breaker and sends its signals to CIBANO 500 which determines the switch response times: www.omicronenergy.com/en/news/details/new-method-for-timing-tests-on-gis-with-grounding-on-both-sides/ The same principle does also work in air-insulated substations (AIS) if both sides of the circuit breaker must remain grounded due to safety reasons. In such case the current is injected into the ground path while a flexible Rogowski coil is attached around one side of the grounded terminals. If you have any additional questions, feel free to contact our technical support team - they are happy to help you: www.omicronenergy.com/en/support/technical-support/ Best regards, your OMICRON team

[@yashiro798]

Many companies underestimate these tests. Usualy, this tests are expensives, because you need especificaly equipiments and workers who are trained to operate and get the best and correctly results. But, one failure on one circuit breaker may cause big loses to companies.

[@deepakkumarparida6355]

Thank you l got some more information about CB test .one request kindly give the test results which varies by aging and is there any book on aging with test results? Kindly reply.

[@omicronenergy]

Dear deepak kumar parida, Thank you for your interest and for watching the video. Aging of circuit breakers has an influence on almost every test result. On further information about interpretation of CIBANO test results we suggest the paper "Interpreting the results of circuit breaker analysis", it contains test examples from new and aging circuit breakers. You can download the paper in the knowledge library after a quick login on our customer portal: my.omicronenergy.com/ Best Regards, your OMICRON team
