Its very weird for an engineer not knowing this when this kind of stuff is taught since in middle school. Seriously, what's the point of paying those teachers when they contribute nothing to students' academic achievement?
Yea, I got an electrical engineering degree that was 99% theoretical perspective and heavy on the math. My class graduated with so little practical knowledge it was hard for any of us to find jobs... that and there was a recession.
Associate engineers r doing some small n little experiments in technical collages n visits of industries are giving broader view to them.....though mathmatics n algebra n geometry n integration is very weak as per subject and students capibility is also little low othervice technical collages curriculum is even have much better standards .................but v need capable manpower to join technical colleges as i believe the person who studied in technical collages n then go for the engineering can be the best engineer for the country inspite of those who just done the engineering after pre-engineering.............or after 12 grade......
I was in danger of being beat up and shot by a Crypt Gangster until I asked him if he wanted to know how a transformer works. Also, had he ever been curious about Nuclear Fusion?? You should have seen the look on his face - he was terrified of me and took off real quick like, getting into the car with the rest of his homies. Whatever he told 'em must have had the same effect c'os they were GONE, and I mean GONE, screeching tires and all!!!!
Excellent so would know the answer to this: After placing the primary coil inside the secondary coil, I assume the coils don't touch each other, what is the size of the gap and if there is anything in there besides air separating them?
It was fine up until the 3-phase explanation and star vs delta configuration. Then it suddenly became an explanation for people who already understood the matter.
I was just in a training session in my countries transmission grid operator and this video was shown. So your content is good enough that it is being used by the actual people operating the transformers.
Found out this channel accidentally and I love it. I love simple step-by-step explanations and the actual models - makes everything so simple and clear. Keep it up!

Jake McCoy ever heard about scaling a transformer down to a book? How should a student experience three phase alternating current or - voltage? Or electric power W, var, VA? Concept of leading and lagging, cos(phi)? Cubic root of three? Frequency? There are so many theoretical things you cannot experience. Try to experience invisible things, you cannot touch. Magnetic fields. Just to mention a few things.
Nice. For 48 years I have been walking the earth looking at transformer boxes wondering how they work and now I know something that i didn't. Thank you.
I am a mechanical engineering student.But i have to study electrical as part of curriculum and u have made it very easy for me with your simple explanations. THANK U SO MUCH😀😀😀
I wish I had this before becoming a industrial electrician . I am glad that it has been made available for the craft in such detail.For the up and comer. Ty.Fortunately I learned most of this. But I still can't put it to paper and retest. Funny how if you don't use it you will loose it. Thanks for the great video !
Very great video! I'm an electrical engineer at his first year job and those videos are very helpful to understand equipment beyond the university blackboard. Who votes for a video on manufacturing process (and difference between the oil-type brother) of dry-type transformer is made?
Very informative. Confirmed my theory as to how transformers work. I had a theory because I couldn't find this information anywhere else, so had to come up with ideas. But I didn't take too much time analyzing the circuits of the three-phase transformer configuration to understand how it works. I've been up all day, and only planned on learning the one thing, and prepared my brain for such, no more. lol I'll come back eventually.
+falling upwards Yeah...it is physics here but on the electrical side, you will not need it in the first 2 years of mechanical engineering ,as a student
Alexandru N. Yea, MechE will likely on have to do two levels of physics. At GMU it basically goes Basic Newtonian --> Fluid Dynamics --> Electrical/Magnetism
we must also describe 2 things: the number of windings affects voltage (more secondary windings that primary results in a bigger voltage), while the resistance of the wire affects currents (lower the resistance, higher the current). thats why transformers can be used to lower/higher both voltage and current at the same time. (at 1:50, if you have enough patience to calculate the windings on the secondary and primary, you will realize the secondary has more turns, resulting in a higher current.)
Iron, wrapped in copper, immersed in oil... that explains the need for a 26-wheel monster rig when moving a transformer that is barely a few metres in size.
for those whom it might help click in their heads: The magnetic field created by the coils travels through the iron core in order to reach the secondary coil.
Learn Engineering Hi firstly I'd like to thank you for such a great video that helped us in our lessons. Secondly, I want you to know that I translated the video into my nativa language (azerbaijani) and added subtitles to it. I uploaded it to youtube as well. If you want I can delete it or add some note about you. I just wanted you to know about it. Regards!
Dear Sir, I think you are wrong mention, HV should be Delta connection, and LV should be in star connection- from this star point, we can get phase to Neutral....Please correct me if I,m wrong...
Power transformers usually have the HV winding star-connected, due to the voltage on the winding is sqrt(3) times lower than the line to line voltage, making the insulation more economical. And although the current in sqrt(3) times higher in a star connected winding compare to a delta connected winding, it helps to make it stronger and overcome high electro-mechanical stresses due to fault currents or inrush currents. For distribution transformers the insulation is not that expensive, then the delta is generally used in HV winding to avoid the circulation of zero sequence harmonics to the grid, and the star is employed in the LV winding to allow the connection of 1 phase loads, for example: to 120V (line to neutral) or 208V (line to line).
well... to be fair the math behind all that explanations is TOUGH af! We are talking about advanced and applied calculus (electricity and magnetism) + some basic electrical network analysis.
Voltage is a force and that force carries current. When the force is high some current loses it track and will eventually destroy the system. Thus a neutral wire is connected so that the loss current will not destroy the system
The only thing I learned in school was the picture at 1:32. This video helps understand the different configurations and the arrangement within the transformer box.
magzire these are all complex configurations but the entire concept behind induction is simple. Like anything really once you know the basics people can become extremely creative. Ask any expert/inventor in any field
The human being you are speaking of is Nikola Tesla. He developed the two-phase motor. George Westinghouse purchases his patent. The entire story is actually quite amazing!! And Tesla was a TRUE genius - not the "90% perspiration" type. ;-)
@@johnarmenta2199 What saddens me the most is Nobel prize committee failing to recognize Tesla's immense contribution to well being of World Community - one would have expected Tesla to be presented with Nobel Prize even post humorously.
I thought the same thing. Then I read Henry Hooker's post. Yes, this would be a GSU. Don't make the mistake this engineer made when I called for the incorrect high-side and low-side windings. Yes, it works, but the generator is 60 degrees out of phase with the rest of the world. So, the entire plant uses secondary electrical power that is 60 degrees out of phase, and it cannot be backed-up or loop-fed from the distribution unless there is a "drop and pick" switching procedure. I'll never make that mistake again!!

The normal way of connecting a distribution transformer, to make the LV-side in a star connection.

Low voltage coils will be connected in star fashion. High voltage coils will be connected in Delta fashion. This is for your kind information.
Low voltage coils will be connected to the delta fashion
Both connected in star formation for accommodating primary and secondary neutral cts

what the purpose of neutral at the high voltages ?
Voltage is a force and that force carries current. When the force is high some current loses it track and will eventually destroy the system. Thus a neutral wire is connected so that the loss current will not destroy the system

Should have mentioned conservation of energy is maintained by a decrease or increase in amps as the voltage is increased or decreased.

And the college I pay for has provided us only a black and white picture of transformer.
Great job. Wonderful explanation
this could have been explained better, they assume people know what eddie currents are and what induction is.

Ths is meant for engg....they mst hve assmed tht a frst yr studnt must b familier wth basics...

He explained induction in the begining and as for eddy current its just another form of induction in the magnetic circuit between the two coils
