As a power plant operator for 20+ years I have racked out thousands of breakers. 2 things, first where is your arc flash hood? Arc flash clothing is great but your face would be roasted. Secondly, where are you remote racking devices? 60 year old coal plants have remote devices. When you read the arc flash rating on switch gear there is a boundary to set-up. With remote racking device you can remain outside of boundary. Another great addition are arc sentry or maintenance mode on switchgear. Changes relay settings for when racking breakers for your safety.
Exactly...there some things in life you just don't do and playing around switchgear and motor control centers without proper PPE is one of them. Remote actuator even better.
Arc flash mode drops for load side. Still potential for line side arc flash energy. However , it would lower PPE requirements , in full agreement with this comment
Not all substations have a auxiliary panel where we can open and close. Sometimes you just gotta hit it with your least dominate hand and turn your face away, or use a “chicken switch” which is a long bendy pole to hit the pistol grip from far away
I love the key interlock system, enforces steps in order to proceed. Very cool.
me too
I hope one of the keys do not go missing. That would be annoying.
This Filipino guy is the boss! He should have much more than 20k subs!
Thank you very much for this wonderful comment
I am retired from working at the Los Angeles DWP Scattergood Generating Station. I have racked out and racked in 4160v circuit breakers and 480v circuit breakers. There was a set of safety procedures to rack in and rack out these circuit breakers that had to always be followed. The circuit breakers at Scattergood Generating Station were older than the circuit breakers in this video.
Please make more videos. Utter respect for what you do for beginners
Thanks for the video. It made me feel more confident while changing the battery of my kitchen-clock!
I've never seen this sort of thing before - the keying system is such an awesome idea that other industries should use - you can't access the next key without all previous steps.
Hey why do we need excitation key, what is normal and DE excitation
That's widely used in the electrical industry
This is one of the most useful video! Hello from Russia, my teacher!
And to think my love of electricity and troubleshooting brought me to this channel and can't get enough now...
It would be realy knowledgeable to be cadet electrician with you sir. 😁
this kind of video must be watching of all youth in this generation... knowledge video so they explore some good things and it will be useful in their life someday... but so sad that all youth today is more attracted to none sense video... vlogger sorry to say to this generation.. goodluck sir keep it up and inspire others that one to learn more in tech world..
Great video, I'm a sparky and I had a vague idea how this works but what a wonderful explanation!
Great video, but gloves always need to have glove protectors on them. Never use the bare rubber gloves.
never even heard of glove protectors before but now i know thanks
@@cliveramsbotty6077 leather gloves always go on top of the rubber otherwise they are one time use gloves per NFPA70E
Great effort sir ...... u make useful vedios which no other ETO do apart from the heavy work u have onboard u
Take extra effort in doing such a wonderful videos and helping others great respect to u sir love u keep on making videos.........
Thank you for your wonderful comment. Please do not forget to share the video
keep your informative vlogs coming you educate many aspiring electrical fans
so useful, i can learn more from this video than from the dudes in my job. thanks sir
master gawa ka rin ng video ng difference ng ACB & VCB. Salamat. Abangan ko yun master👍
Nice video sir.. Very informative and helpful.. Bka meron po kyo video ng replacement ng crank angle encoder, mpc replacement at me overspeed test.. Thanks in advance..
nice one boss..ganyan yung work ko sa dubai electrcity..more power

Great job sir. Your videos are very helpful. Love to watch more videos from you. Thank you.
awesome bro, I am going to join ETO Course coming march,. It Will definitely help me in future .....
Thank you for portion out of your actual experience and idea.
Thanks a lot for making such videos. Its really helpful for us . It also enhances confidence in us.Thanks.
Thanks for the video sir. It helps me a lot for my MHV training
Nice one! Why rack out the VCB...Was it faulty? and how do we tell when it's faulty?
Video for the reason will be uploaded soon
Awesome stuff doing this in college in high volage with sf6 gas circuits breaker
Very useful electrician from zimbabwe
Thank you. Regards
Hello sir, before disconnecting VCB do we remove supply to that particlar busbarto which vcb is connected?
Sir please make a video of synchronization of generators please sir i am big of fan of u from India 🇮🇳
What ain’t you wearing Arc flash suit only 7.5 KV gloves were used while rack in rack out ??? What is the protection if there will be any flash over while Rack in ?
sir just want to ask, is there a specific counting of turns when racking-in the vcb?
Sir ang galing nyo po sana ma experience ko din yan low voltage po kasi minimaintain namin ,,
Kirk key interlock for safety operation. Thank you for sharing this video. 👍
Sir, what specific job have you done after drawing out the VCB?
Those are interesting looking keys at 02:00 . Cool video!
I have worked on 6.6 KV always check everytime so no mistakes
May I suggest that if you want to refine this video, please include "turn the Local/Remote switch to Local" before you start the isolation process and only turn the "Local/Remote switch to Remote" when the Circuit Breaker is in Service position. The purpose being to be in full control of your switching operations. If you have competent persons working at the Marshalling box, there is a possibility that they may short two points to close the Circuit Breaker accidentally remotely from where you are operating the circuit breaker, don't you agree? Part of reason for Lockout and Tagout is to ensure there is no chance of erroneous switching during switching operations. My thoughts as an Authorised Person for voltages up to and including 22kV switching in Singapore. Anyway thanks for your sharing of circuit breaker operations. Have a great day.
Sir do you ever experience over feed of vcb?..if yes what counter measure you apply?
the vcb has always protection for over fee, reverese power and preferential
No worry of arc flash during rack out procedure? Take care nice work! Good video
Sent from USA 🇺🇸
No mate because the system was already isolated, grounded and disconnected.safety first
Arc flash gear is necessary until the system is verified dead. Looks like this fella verified the system dead by earthing it. Oof. All it takes is one missed lock and you’re another arc flash horror story.
@@johnangelodelacruz6431 Hey why do we need excitation key, what is normal and DE excitation
Appreciate lecky jake:salamat sa info
astig sir... thanks very informative
tq for the sharing sir.. hope to see more vids from u sir 👍
NFPA 70E gloves without leather can only be used once. No flash shield or balaclava. Arc flash potential in that cabinet most like requires 40 cal suit not 12 cal stuff it looks like he's wearing.
hi! Which name your vessel ?
Sir could you please .. provide a cc caption below the video..it will understand easily 🤗
Thanks for sharing the procedure
Nice job
Thank you for sharing. Now when my circuit breaker in my home trips I'll know what not to do to reset it 🤣🙃
Me encantaría trabajar como tú ayudante
Hi, did the busbar side is also deenergized or only gen side?
Bus bar is always energized
@@leckyjake thanks, you the best
Hi I Like your video. Thanks
Really interesting to see ship electrics!
Excellent video, thank you very much.
nice video... keep safe always po and keep it up...
Thank you very much sir we learned a lot on your channel
Thank you very much for your support. Please do continue to support my channel and do not forget to share
Nice learning bro.
Sir, how about bucket type circuit breakers (low voltage breakers) if you have any, Thanks.
sir which camera for shooting?
Hello Sir, how to apply to be an electrician on board? What are the processes?
Super interesting, thanks!
what's being grounded? the enclosure?
thank you for sharing. your knowledge sir
What is the purpose of de excitation key
Thanks for the video! Looks like the inspection on your gloves is expired. They need the be inspected annually or after each use if not using the leather insert. You can get little pinholes in the rubber. Your company needs to do this for you, and in the US is a big fine if they don’t.
We have spare and the expiry date is always written on the boxes. We are serious in dealing with safety.
Watching you is like watching a Resident Evil walk through... use this key to unlock that door to get that key to access a port to use a tool that then frees another key... lol
Thank you for watching
its same function of my work as electrical maintenance in industrial plant.
Greetings from Mexico my ETO friend, great videos
Thank you for the support. Please do not forget to share the videos so that we can help others too :)
@@leckyjake done!
That’s so nice of you.
God bless u Lecky jeck... U will be at big possion one day.. thanx for video... Keep making videos... Nd keep spreading love with us
Nice explanation thank you 😊
Nice video 🙂good work
THANKS IDOL
What is really the grounding in a vessel the body of the vessel itself or anything else like any elctrode or cathode which is touching the sea water ??
I guess it would depend on the coatings applied to the vessels...I know most saltwater sea fare worthies get ablative paints to their hulls, which shedding of electrons is how they peel off old dead cells to expose better layers of protection in the paint layers. Depending upon the voltage class we're considering in this conversation and some other factors, I would venture to say that the paint layers constitute some form of insulation. That said, I'm certain no vessel is sealed completely along every single facet of it's structure and ports, etc;. I don't know all the intricacies of those ships though...not certain the practice out there on the water but I would think, just like on land, bonding all of the metal structure to bring to water potential would be the ultimate and to achieve that a 'designated grounding electrode', perhaps something altogether separate from the hull would be the order of the day.
Thank you!
Hey folks you should really wear arc flash (not fr) Ppe including proper rated face shield and balaclava
if u dnt mind sir, why you need to racking out the VCB? AND what is the purpose?thnks.more power,godbless
You will find out in my next upload. VCB troubleshooting
I have no idea what any of this is so forgive me when I ask what exactly goes wrong that requires this procedure?
Sir anung specific training kaya kelangan pra matutunan yan?.. Tnx
Marine high voltage sir
Thanks 🙏🙏🙏🙏🙏🙏
Where is this?
Grt job bro. Can u pls write the steps??
No face protection?
Eto job onboard keep safe.
Make a video on DG syncronizing
Maraming salamat sir
Awesome video sir!!
Thank you
Before racking out VCB you have not shown us the spring discharging by pressing push button....
you dont discharge the vcb when it is racked in. You have to rack it out first.
can someone explain me how the heck you have high primary voltage in a ship WITHOUT watertight switchgears any water leaks in those rooms would be a death treat to any worker near by! need an explanation here?
The room, the engine room, the engine control room and all entry points are watertight.
Super sir
Maganda Sana Kung Tagalog nalang para intindihan nila.. salamat SA magandang tutorial
Sir apart from ACB and VCB do we have other types of ckt breaker and does every ship have Vcb
you have SF6 breakers also
Sf6 not used in ship it liberate hazard gas in closed space mixed with air
SF6 gas itself is not toxic at all yet until it burns and that is super toxic. So whenever there is a S/G explosion, do not enter the switch room unless you are putting on proper respirators. It’s Hazmat zone. Toxicity. FAULTED SF6 GAS - Faulted SF6 gas smells like rotten eggs and can cause nausea and minor irritation of the eyes and upper respiratory tract. Normally, faulted SF6 gas is so foul smelling no one can stand exposure long enough at a concentration high enough to cause permanent damage.
It is a potent greenhouse gas with a high global warming potential, and its concentration in the earth atmosphere is rapidly increasing. During its working cycle, SF6 decomposes under electrical stress, forming toxic byproducts that are a health threat for working personnel in the event of exposure.
Where is the face shield helmets?
Hey why do we need excitation key, what is normal and DE excitation
Где защитный экран, почему спецодежда расстегнута !?
no arc flash gear?
Hey why do we need excitation key, what is normal and DE excitation
No need
Might want to keep the racking handle off your leg and only let it touch your gloves.
Why you not shows the steps to switch off the breaker.....
It the VCB is opened then it is isolated to the bus bar
tysm boss
ano ung main trouble un lecky..
Whereis high voltage ppe?
He is u r assistant ETO sir ? 🤔
Nope he is the 2nd engr
@@leckyjake sir I have funny doubt there will hot water for bath because in rainy time it's too chill to bath cold water 😂
