▶️Introduction
All of the parts related to electrical transformers are discussed in this video.
Transformer Core
Thin laminate steel sheets clamped together to form a steel core. The core focuses the magnetic field.
Transformer Windings
Copper or aluminium windings allow current to flow. Current is induced in the secondary windings due to the magnetic field created by the current flowing in the primary winding.
Transformer Bushings
Used to connect the transformer windings to the external electrical circuit. Usually bushings are manufactured from Porcelain.
Transformer Tank
Used with hermetic and conservator type transformers to house the internal transformer components.
Buchholz Relay (similar to gas actuated relay)
Alarms and trips depending upon the type of fault present within the transformer and also if the insulating liquid level becomes low. Learn more:
• How Buchholz Relays Work
Radiators
Used for cooling of the transformer insulating liquid.
Magnetic Oil Gauge (MOG)
Used for measuring the insulating liquid level within the transformer conservator tank. Learn more:
• How Magnetic Oil Gauge...
Temperature Monitoring and Measurement
Used for measuring the transformer insulating liquid temperature and for controlling the cut-ins and cut-outs of pumps and fans etc. Learn more:
• How Transformer Thermo...
Silica Gel Dehydrating Breather
Used for drying of the air as it is drawn into the conservator tank. The oil cup at the base of the unit is used to filter foreign particles. Learn more:

You all probably dont care but does anybody know of a method to get back into an instagram account?
I somehow lost the account password. I would love any tips you can offer me!
One of the best video on UA-cam related to transformer...Thank you for making it
really appreciate your efforts. Hats of guys.
I am a lowly 'low volt' (120/240v 1ph; and 3ph) residential and commercial (some industrial) electrician in South Florida. This is the first time I have really read/seen/heard ANY detailed information on transformers and their design and operational characteristics. Very, very interesting, entertaining and informative.
Thank you.
There is a guy named Mousa Al Manasif [2 years ago, from now 01/02/2022[], who complemented and thank for this presentation - but brought up a few things where he says there were a few incorrect statements made in this video concerning:
"However I noticed two things that are incorrect:
1- OLTC on load tap changes are divided to two parts
a. Diverter switch ( the arcing and the interpretation of the current, have separate compartment)
b. selector switch ( the part inside the TR main tank which shares the same oil of the TR)
OLTC diverter switches ( are always separate from the TR main tank
2- At the end of the video OT ( oil temperature gage) the red Needle is only a memory needle to show the highest temperature recorded by the OT.
When the black needle ( showing actual temperature) moves up it will move the red needle along with it but when the temperature goes down the black needle will go down the red needle will stay at the maximum temperature the OT recorded so operator can see it during there inspection".
Could you comment on this. And if he was correct: Are you looking to create a revised version of this video; or add an addendum that addresses these things one way or the other?
Either way, the video was superbly done.. Thank you again.
Both comments are correct.
Diverter switch compartment is separate which contains its own oil. During tap changing operations (raise/lower), selector switch contact is selected first and then diverter switch contact changes its position from odd to even or vice versa and desired tap is selected.
Great! Refreshed knowledge I had 35 years ago as a fledgling 11kV Authorized Person. Might have mentioned operationally that certainly oil cooled transformers can usually accept short term overload periods considering a 24 hour duty cycle. Finally, let's hope all "Pyrochlor" PCB oil has all been safely disposed of. Beware also that toxic brew was also used in early fluorescent light ballasts that might still be lurking in our sheds.
Out of all the comments made here this is one of great importance. The use of PCB's was widespread and there is undoubtedly many transformers lurking around with this free cancer toxic soup. It was also a very good thing to mention those old magnetic fluorescent lighting ballasts with the potted black toxic tar in them. I have come across many of these in the past. It helps to be wary of the potential dangers of these to help protect yourself from them and hope others see the importance of this. Excellent comment and Thank you.
thanks for the best video ,this video is lot informative than a standard text book
Well explained and illustrated thru 3d animation,I learned a lot thru this
GREAT video. Thanks.
Thank you. Super helpful!
Very clear and helpful lecture. Thanks a lot.
brilliantly explained!!
Great video, very clear and informative
wow... man what a great video. this is exactly the kind of detailed material im looking for. subscribing.
Welcome aboard!
As a new engineer in utilities, your videos are far better than anything I've learned on the job or in my schooling. For 9.99 euros i feel like I will be stealing from you. We get emails for courses all the time and they're always like $500 usd. Doubt my work will pay me back but for 9.99 it's worth it
Beautiful, very good presentation. Clear explanation of the content. Thank you so much.
You're very welcome!
fantastic work dude
lots of love for this channel
I want you to know... I'm learning a lot about transformers. Thank you for your expertise.
Excellent visual presentation
Thank you for this information
Well explained. Thank you.
Thank you for a most informative explanation well presented.
excellent task! a great service for the learners indeed! thanks
@@savree-3d plz make vdo on alternators and combined cycle plant.
wonderful, keep up good work

Commercial & Resi Sparky here. Trying to teach myself about transformers and this was an excellent video. One suggestion would be to have a video on how they are installed & hooked up.
Thank you so much...This video is very much informative and useful....
Thank you so much:)

Thanks for sharing your Knowledge
great starter video
Perfect 👌
Amazing video
You are the best
*Very nice and helpful video for us, because we manufacture oil filtration machines and oil testers for transformers.*
Otimo video, recomendado pelo professor ailton
Great job bro
I like the video. thanks for sharing
I like this video!!!
this channel is awesome..deserve waaay more subcribers
Thanks! Tell someone about us, best way to help us grow!
Perfect......👍🤝
Thanks posting
Good video and educational. There is a minor difference in terminology with respect to what the narrator called the limbs of the xfmr, whereas in the US we called those legs.
Namaste Savree Team, this was really an awesome video. Can i know how you made this animation?
🙏thanks you
Kudos...
Great presentation. Thanks for this.
Glad it was helpful!
Good one
Nice video 👍
Very comprehensive. Thank you
Glad it was helpful. Have a fully configured transformer on the website now and its quite cool to hide/show various bits. Pity it was not ready for this video really.
@@savree-3d pity indeed ☹. Will it be ready any time soon?
awesome bro
thanks for the video.
You are welcome
Woo nice video
thank you
This is very educational. Do any (or can) any of these components out off an odor? I live near a substation and have noticed a foul odor that almost smells like old, spent oil. It is very bad smelling and pretty overwhelming.
Good work
Very nice introduction. A good supplemental video project could be made on Grids and Transport.
Air/sub soil/sub sea line systems, TN´s, TT, IT and so.
I found your Francis Turbine and Induction Motor. There is still openings for making projects on Generators, Breakers & Relays, for a full basic intro set.
Great explanation
Glad it was helpful!
smart explain
Tq so much
Excellent video....
Thank you!
INDEED, THIS IS GOOD INFORMATION !
Excellent explanation.

I cannot thank you enough
Thanks for watching.
អគុណបងthank
excellent one
Many thanks
Great video indeed as many others have said. BUT there's only one major component that wasn't mentioned and I only know cuz I work in the utility industry. The CTs that are wrapped around the bushings. Very important piece to monitor the current flowing in and out of the transformer. And for protection.
Absolutely true. We totally forgot when making the video. It will be added when the video is updated.
Excuse me Sir, can you explain us about High series capacitance winding ? Which is used in power transformers windings, exactly in High voltage windings. With my best regards.
Good
which software do you use ?
This video contains all information about transformer, very useful video. Thanks for this video

Superb explanation
Thank you 🙂
Excellent explanation, consider my one like equal to 1000 👍. Upload similar for reactor, cap.bank and earthing transformer etc..,
Can anybody mention here about pre Commissioning test of breather and off load tap changer?
Sir,Which software you had used for designing this model??
you said that the high voltage side has the big bushings and the low voltage side has the small bushings although the high voltage side has the small amount of current and vice versa and another point , the high voltage side according to you has the neutral and i think it is in the low voltage side
Hope to see a video explaning all the components of a circuit breaker, specially in the power electric industry. Thank you!
@@savree-3d Yay! =D I've been enroled in your course too, it's been great. Just missing this part talking about circuit breaker. Thank you.
This is helpful.
regaurds.
love the video so well done what software did you use to make the modles
thank you for this video; please what does it mean when you have a depression in the transformer tank

There is insulator between the HV windings and LV windings, this could be shown
Very nice gas
the link to the oil analysis pdf is dead. Your comment about how the gasses can be an indicator of fault, would that pdf have discussed those characteristics? I'm super curious about that. Thank, sweet video.
@@savree-3d ohhh that sounds exciting. I'm such a nerd. Why do I can about transformer oil analysis LOL
26:39 the red needle is just a max indicator for temperature
Correct. The red needle is also known as a drag needle which shows the highest temperature the top oil has seen. This needle can be reset to the ambient temperature. In this example, the alarm and trip values are set using the four "rings" seen below the dial. KB
Superb explanation! one question though: at 25:05, you explain that sometimes the 'transformer' is mounted outside the transformer tank, do you mean the 'tap changer' rather than the 'transformer' is sometimes mounted outside the transformer tank? Thanks!
Sorry, yes, it should be 'tap changer'.
Please make video on this
Hi friend
Wich program you make it??
if you make some 3D for 650KVA or 150KVA commercial substation , transformer , PIF , LT and HT
Add PRV working .
