11:05 The reason that the transformer core is a bunch of laminate (insulated) metal sheets instead of a solid piece of steel, is to reduce magnetic field eddy currents. The purpose of the ferrous core is to merge the two coils' fields for greater induction efficiency; however, each electrified coil is turning the ferrous core into an electromagnet; and THIS electromagnet produces an additional magnetic field (the aforementioned eddy current). This eddy current works against the efficiency of the whole system! So the solution is "divide and conquer" and use several very small pieces of steel which are electrically insulated from one another, and this prevents the core from becoming a giant electromagnet (but rather numerous very weak ones).

I work as a generation dispatcher in a secure control room and this video really helped me understand how electricity is transferred from our generation stations to the individual residential consumer. The idea of transformers wasn't very clear to me until watching this, thank you!

I am an electrical engineer but this video was much more helpful than my school's notes. Really nice work!!!

[@pedrogouveia9884]

Great overview of the eletrical grid. Video with a fantastic quality and very pedagogical. Well done! I'll definitely follow another ones.

[@ahmedalmazrouei234]

Excellent explanation even for beginners from outside this industry. I believe these basics are enhancing every one’s knowledge. Keep it up and thanks for your efforts..

[@ismaelmetero4121]

Amazing. As a software engineer i never could wrap my head around electricity.... but I clearly understand this explanation.

[@ericaasen4512]

I've been in the electrical field for 22 years. I've taught electrical theory and I run large commercial projects. This is a good, detailed explanation. Good job

[@omkarpatel4599]

[@jlacko]

Hoping you can answer two questions I have on this topic: 1) What happens to electricity that is not consumed by the end users of the line? 2) How much extra energy is produced by an average grid as to prevent brown outs in everyday demand on the grid?

very informative video. if you will be able to show me working of switchgear, it will help me a lot.

[@vittoriopiaser9233]

I have a doubt about the losses’ entity. Known that power lost is PL=R*I^2, we also have I=V/R, so PL=V^2/R. R remains constant since it depends only from the material properties and the wires’ length and diameter, so the losses also go with the square of the voltage. Hence why is it actually more convenient to use low current and high voltage?

[@netional5154]

Very good point and somehow seldom properly explained. When they talk about high voltage, they mean high voltage compared with the ground. So there is a lot of excess charge in the power lines. However, the difference between the excess charges on one end of the power line and the other side is very small. This means that the voltage difference on just the power line is very small, hence also the small current.

[@noname-ug2qx]

Isn't the Primary Consumer voltage supposed to be 0.4kV?

[@FirstnameLastname-fn6ik]

I'm a little confused about the relationship between V=IR and P=VI. With P=VI, increasing the voltage means current goes down because power is the same, but with V=IR, increasing the voltage means current goes up because resistance remains the same. So in a step up transformer, if the secondary coil has a higher voltage and lower current, doesn't that mean it must also have a higher resistance than the primary coil? Otherwise V=IR wouldn't be obeyed because V is going up while I is going down, so R has to make up the difference.

[@ohgoditsjames94]

Ohms law only applies to completely resistive circuits, transformers aren't purely resistive as they also have a magnetic component, with the core being a magnetic circuit and the windings being inductors, hence they have inductance values, it's quite a complex topic to explain, but I suggest searching "transformer equivalent circuit" and you'll get your answer eventually lol.

[@CLEFFJOE]

Mechanical force + electricity = Magnetic force............. Superconductors uses this principle to generate magnetic force used to power Maglev trains. Magnetic force + Motion = Electricity................. 3phase AC generator uses this principle to generate electric power. Magnetic force + Electricity = Mechanical force....................... Motor uses this principle to generate motion & it is used in power tools, vacuum cleaners, turbines etc.

[@MrTommyboy68]

As a side note, out electric grid here in the US is SO FRAGILE AND SUBJECT TO MASSIVE FAILURE due to the LACK OF MAINTENANCE AND UPGRADES over the past 70 or so years. One TRILLION dollars would not be enough to completely upgrade the system. Expect more and more "power disruptions" and LONGER "outages". People have no comprehension of how expensive towers are, transformers are, permits and right of way issues, and everything else associated with electricity generation and distribution. All they care about is that their A/C works and their refrigerator works so they can have cold martini's.

Why can't the transmission lines be insulated by plastic instead of air(13:20) ?

[@savree-3d]

You could, but it's not needed. You would also need a lot of plastic.

[@anphan6905]

[@stephenbrickwood1602]

How many klm in the national grid. How much does the grid cost to build per klm. Why build more than one line of transmission towers. Just use one ? Did the national grid take a century to construct ? If no fossil fuels in the future do we need 5 times more electricity, 5 times more grid capacity and 5 times more generators ??? I think that the grid is the killer cost to an electrical grid future. Great minds discuss ideas.😊😊 Average minds discuss events. Small minds discuss people.😮

Electricity is managed, not "manufactured ". High voltage dont require a constant imput of coal or gas to boil water to make steam to turn some massive generator that "pumps " current along a billion miles of wires. Instead high voltage is balanced in a resonant loop and is coupled to ground through transformers. The current that runs our devices strictly from the secondary coil of that pole transformer dont "draw " energy from a frickin fuel fed machine. There is no physical wire connecting our stuff to anything pass this point. The flow of current to ground is as natural as lighting . If theres a proper air conditioner, heater , stove ect, in the way , oh well. There's no doubt ,to design buid and maintain the grid is costly. Now days computers controlled voltage regulators and what nots are managing the show , theres really no need to have some guy turn the big power dial up or down .
