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!!!!

[@alchemy1]

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?

[@-danR]

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.

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......

Thank You for breaking it down it and explaining it so clearly with a video .

[@krashd]

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.

[@magset]

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.)

As a graduate power engineer I've never been demonstrated how physical transformer works. Such video like this is not a free from my views but, thanks for your free gift over. Well played and fully understood

[@Shitmusket]

Actually the high voltage side is usually in a delta configuration and the low voltage side is in star configuration. The delta configuration allows us to transport power without the use of a neutral, saves some money. And the star configuration is needed for a ground reference, otherwise the consumers do not have a voltage potential difference.

[@Re_view_]

true

[@combinedengineering7506]

Very true for a step-down transformer, but this one is a step-up transformer.

[@gvcallen]

An interesting note is that in some rural areas the delta just goes straight to the consumers and they tap off from two of the wires directly

[@MrTonyshit80]

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...

[@constantinenomidis4972]

You are right. Congratulations

[@MrSbole]

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

[@eduardoalbanez2052]

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).

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

this could have been explained better, they assume people know what eddie currents are and what induction is.

[@MrArray1967]

Bradford Hart. Learn engineering says it all. You have to start at the beginning.

[@playlistz4042]

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

[@sahincangaz3989]

Eddie current is the current which occurs under the condition of alternating that causes magnetic induction(due to changing N-S poles). Eddie is an opposing current inside the conductor material to the external magnetic field hence it lowers the efficiency. To reduce eddie current loss, Engineers basically use the simplest principle V=I.R in electronics. They deliberately rise the resistivity of the conductor material by laminating several thin sheets and insulating them each other. Finally, each laminations have own small eddie currents but when they are summed up , resistance gets higher.

what the purpose of neutral at the high voltages ?

[@ckarmakun516]

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

[@henryhooker2770]

This is a step up transformer and that is normal for generation plants

[@johnarmenta2199]

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!!

Transformers are like a tank. If you step-up voltage, its like filling a tank so current decreases while voltage increases. If you step-down voltage, its like opening a faucet so current increases while voltage decreases.

I'm pretty sure the basic formula to know if the power is a drop or increase is by doing the primary spins over the secondary spins. This would mean if the primary spin is at 5 spins and the secondary spins are at 10 spins then the total voltage drop will be reduced by half. Shown as 5/10 or a half. In the video, I'm pretty sure you say the opposite. More spins in the secondary the more power we have. You show in the video more spins being added to the secondary spool and say voltage increase. Please tell me if I'm missing something.
