Please let # ElectroBOOM play with this transformer!

I need this buck converter for my next arduino project

"Hello, Power Company. What's the issue?" "Our transformer just blew." "Oh dear, we'll send a line crew out right away." "No, you don't understand..."

"the future looks bri---" *transformer explodes, killing narrator*

The rule of thumb is that electricity will arc (not plasma, where the current increases exponentially in ionized, conductive air, but in non-ionized, non-conductive air) 83,000V per inch. At 1,100KV, the arc will travel many feet. Therefore, in order to prevent the electricity from reaching ground, it must be insulated on very long, heat-tolerable ceramic insulators, or bushings. The bushings must be heat tolerable because it is not just voltage in the electricity, but also thousands of amperes of current which produces higher heat as the current increases. The bushings are designed to look like bee hives, or discs, because electricity travels along the outside shape of the insulator, called the skin effect. This is a natural characteristic of electricity. So, shaping the bushings in discs makes the travel path longer. The alternative would to have extremely long, straight bushings. But with disc crests and troughs, the electricity travels along the shape of the discs, which is a longer distance than straight along a smooth, straight insulator. The ends of the bushings are smooth, large rings to reduce the corona effect, which is leakage of voltage into semi-conductive humid air. Air contains water vapor to different degrees, depending on the weather. Water is conductive. Any corona effect or arcing of electricity to ground will reduce the amount of available electricity to the source and, thus, reduce the efficiency of the transformer. Also, arcing causes, as with lightning, the air to become ionized (the oxygen in air gains an extra electron, which it does not need, and thus allows it to travel from one oxygen atom to another creating a conductive path), which allows high current flow from the transformer to ground. This also will ionize and remove the conductive metal that the transformer is made of, slowly destroying metal terminals of the transformer. Since higher power (voltage equals power divided by current) and low frequencies (power is transmitted at very low frequencies of only 50 Hz or 60 Hz) require larger transformers, switches, relays, circuit breakers, wire, insulators, and other things found in a substation, the transformer must be large. This is because the larger size of the transformer allows the transformer to dissapate heat, prevent arcing, provide enough metal to allow high power flow, provide enough distance between the power and ground (through the large insulators), and prevent the corona effect. Such high power would consume and completely destroy a transformer that was too small to allow an inch of insulation per every 83,000V. Electric energy, U, is equal to capacitance (the ability to hold a charge) and voltage. A coulomb is equal to an ampere of current per second. Both a coulomb and electric energy increase with an increase in electrical power. Coulomb, U, C, P, V and I all are characteristics of electricity that require larger-sized electrical components to provide proper transfer of these characteristics without any losses. A large-size transformer also has room for current-sensing transformers to be placed on them. These smaller current-sensing transformers give a direct, meter readout of the current flowing through the transformer at any one time for the linemen monitoring them during the varying loads placed on the electrical grid during a day.

Quantity of insulation also increses with increase in voltage rating. That's why size of the transformer increases .

For all the people that are confused about hearing a DC transformer: Pls note that the Transformer's name is UHVDC transformer (Converter Transformer). It is used in HVDC converter station that's why it is called as DC transformer, although the working principle is same that of AC transformer (Mutual Induction).

Looks like some kind of death machine (electric impulse canon) X-D

The overall size of the trf increases with voltage rating because of 1) Increase in insulation thickness and duct spacings between HV and LV and also LV and ground(tank). 2) increased Bushing length due to very high air clearance to tank surface and also it's application in hvdc to counter tracking phenomenon owing to higher pollution levels in hvdc environment. High power rating too contributes to increased size of the transformer due to heavy windings to carry high currents and higher magnetic clearance requirements to avoid eddy current heating of the transformer tank.

When you need to step up and down those lightening strikes

I'd like to see the 1100kV rectifier.

Transformers increase in size, in relation to higher voltages due to the amount of coils or wraps needed to create the proper amount of impedance. If the impedance was too low you would create a dead short. More coils more bigger. Also air cooled transformers are bigger than liquid cooled transformers.

The bushings on this transformer look like the main guns on a dreadnought!

12 gigawatts? About 10 times the energy required by the Back To The Future's time machine. Please someone call Doc, now we can do time travel easily :-D Jokes apart, this is truly a massive beast of a transformer. Impressive.

the size increase is primarily thicker insulation to contain those higher voltages.

Transformers: More than Meets the Eye!

I have this model as an USB-stick. It was gifted to me when I was at an Info day by Siemens in Erlangen.

The tranformer need be that big because we are talking about 1100kV , that is 1,100,000 volt. To get a voltage that high one need have many more windings compared with the primairy input. Generators are giving power in watts, but for this let's assume we do have a generator that has 1000 volt input, then you need to convert 1 winding to 11000 windings. One winding is not enough at 1000 volt, the resistance is too low and the eddy current is not '' blocking '' the flow. Use 1000 windings on the primary you need to have 11000000 windings on the secundary. Resistance can't be too high . otherwise the current won't flow freely without generating a lot of heat. So the wires need sized to proportion. The coil windings, diameters and resistance balance. The need for a big transformer.

This is why aliens don't visit us

I remember hearing a year ago about scientists reaching 1 MV potentials at scanning electron microscope. Well now i see similar energies, but with thousands of amps. That's so cool! You probably can power a mass driver with a single one

Photonicinduction my boii, where are you at? We need you to play with this one.

Lets put a 3V motor on that LMAO😂

Well now i discovered a new way to flex, just throw your biggest trafo out and watch everyone with superiority LOL

I'm not going to enter into this room for any amount of money

Styropyro would probably kill for something like this. Imagine the massive arcs this thing could produce.

Siemens dont play ..bravo 👏👏👏

Maybe because of the high voltage generated by the transformer is directly proportional to the number of turns in the secondary coil. And the amount of current flowing through the primary coil of the transformer have some relation with the thickness of the wires in primary coil

Fans of "Phineus and Ferb" will recognize this as Dr. Heinz Doofenschmirtz's latest invention - The Tranforminater.

Good, increase the voltage and reduce the rate of flow of current, This is a main reason to step up to 1100 kv

The tank and most of the transformer was made in Croatia factory name KONČAR then transport to Germany to be assembled. I know because i was working on them,and its a pain in the but to build that monster .

Looks like it'll open up a tear into another dimension or into another galaxy.

Higher voltage transformers necessitate larger sizes due to the need for thicker insulation to prevent arcing, increased surface area for heat dissipation caused by higher currents, and larger core/windings to accommodate the increased magnetic flux. Additionally, stronger materials and structures are required to withstand the higher mechanical stress, and safety standards mandate larger dimensions to prevent electrical hazards.

Just what I needed to power my amp!

Why does the transformer size increase with increase in voltage rating? What do you think?

Two factors - 1. Higher level of insulating material 2. More conductor coil to limit the per turn volt

Seems like it would be cheaper and easier just to build it on site in China inside a temporary building where it's meant to be used. Kinda like a 200 inch TV, eventually you reach a point when it's cheaper and easier to get the tv first and then build the house around it.

12 GigaWatts!! Just get how much power that is.

That thing looks like a cannon from some scifi space warship

Optimus Prime: "So... what do you do after work, babe? [smiles]"

Michael Bay should’ve added a scene where a Transformer is transforming into a Transformer

"Locke" hat's im Griff. 💪

I thought it was going to be a Tesla Mammoth tank.

12 jigawatts??? That will get us everywhere we want to go.

3:20 my man winked at the camera lol

11 Gigawatts! That whats I need for my Flux Capacitor!

1100KV Direct Current transformer? Must be new cause all the trafos I've used only handle AC current.

The question was: "Why does the size of a transformer increase in voltage rating?" Answer: Because Godzilla has been eating up volts ever since the 1960's, and the Chinese just can't have that or else they won't have enough left over to make a pot of coffee. So now they made a transformer that's too big and heavy for Godzilla to simply walk away with. Now if he wants it he will have to call on Jet Jaguar for assistance, but last I heard he was married and is settling down.

From Kenya. I believe the insulation challenge will make the transformer very large

I am EEE student proud of it😍😍😍😍

I would like to see circuit breakers working with this huge high voltage and tremendous watts. Could you please post videos on that subject

Transformers core losses (eddy current + hysteresis loss) based on Transformers is kV rating or Voltage rating . Whenever the voltage is increasing size of core increasing . In other words( Eddy current formula) Pé=Ke*V*f^2*t^2*Bm^2 Hysteresis loss formula Ph=Kh*V*f*Bm^1.6 From this equation we can understand that Voltage raises ,then iron loss raises, and also core loss raise. Hence automatically Transformers size also increasing...

More rating means More Voltage means More No. Of Turns means More Copper means More Heat meant More Cooling means More Insulation On Windings Means More Size.

Imagine if somebody was electrocuted with 1100KV. I think they would pretty much be vaporized

The Chinese reverse engineered it.

Size of transformer increases with increase in voltage because voltage per turns is directly proportional to the net iron core area. 2 . As net core iron area increases the insulation used for transformer also increases

Wow, this thing is more than meets the eye.

As per fardays law of EMI the induced emf in secondary is directly proportional to no. Of turns. Since the voltage at secondary of xmer is 1100kv so turns also proportionally going to increase. Also insulation to this turns also takes more space,hence with increase in vtg rating transformer size increases. Thank you

I read somewhere that the circuit breakers on the 1100kV DC have to break the equivalent of a 38 tonne articulated lorry crashing into an immovable object in the event of a short circuit. Fantastic engineering achievement the 1100kV circuit breakers.

I don't know why youtube recommended this to me now..But let me try to answer the question at the end. The KVA rating of a transformer from output equation is directly proportional to 'Gross Iron Area' ,which means the cross sectional area of Iron core, and the 'window Area' ...So area being (length)^2 ...area*area means (Length)^4.....so KVA rating is directly proportinal to (length)^4....That means if we double all dimensions....Volume increases by a factor of 8....and KVA rating increases by a factor of 16.

At voltage over 1,000 KV you not only have to worry about corona discharge but x-ray discharge as well.

At first I thought it to be somekind of futuristic weapon sort of Railgun........I'm dissapointed

To get high voltage the transformers required larger no of turns and due to increase in coil it's size increases also. We can get high voltage in less size also than this transformer but that transformer do not show more capacity than that due to less current formation because of it's less no of turns in the coil. So, please reply me that something is true in this or not . Thanks.

It's all about insulation when working at high voltage. After some point, special material are needed which makes it much higher cost, and the most obvious, the size.

What a mammoth ! A great feat !

4:39, *bcz voltage depends on number of turns* *This t-former has 6,600,000 turns & it takes too much area*

The name is Siemens, not Ziemens.

Size of transformer increase with voltage rating, b'coz According to emf equation E=4.44 B A f T If we want to increase voltage, then we increase area of core, b'coz B is constant (1.7 to 1.8 for CRGO Steel), Frequency also constant and No. of turns increase with increasing area of core So that's why size increase.

Gotta love some high energy electrodes, pumping out their Siemens

did he say direct current?

"Feed into a transmission system at 1100KV DC? " Really? I thought transformers were fundamentally AC so does this include rectifiers? nothing technical in this video just Logistics of moving a huge object

It looks like something out a Bond movie. Great stuff.

12 GIGAWATTS! Great Scott!

I just wish he wouldn't call them 'zeemens'

Nothing like a self-congratulatory promotional piece. This is by the same company that squashed a small, privately funded effort to be the first to power an electric aircraft across the English Channel just so Zeemans could get all the publicity for being such a wonderful company.

its the larger size of the wire to handle more current which increases the size of the transformer but the windings stay the same to hold the same voltage.

As rating of transformer increases, higher voltage is required at its primary and secondary side. Hence, to keep flux constant (to prevent core saturation), core cross sectional area increases according to E=√2πf×PhixAxN. Hence, size increases. Also, transformer loss also increases. Hence, to prevent hotspots, size increases.

The out put is the directly proportional to magnitude.

Siemens the king of electrical Engineering

Sooo, finally a power supply worthy of the 3090!

Because of the voltage? At that high of voltage it need to be well insulated from the case. Lol

Higher voltage, more insulation, Bigger core, bigger everything.

Transformers increase in size as the increase of voltage is needed due to the amount of coils or conductors needed for inductance between the primary and a secondary. Thus more voltage = more layers of symetrical conductors needed to increase voltage.

Even when it is filled with oil the 1100KV needs quite a bit of distance between the windings and the side wall of the housing

I want this in my backyard

An increase in voltage rating requires an increase in clearances and dielectric strength. Since the dielectric strength of current materials is constant, size has to change in order to provide adequate clearance. This you will learn form 2nd year electrical engineering trade mathematics (in Australia ).

As we know, Emf is directly proportional to flux, and flus is proportional to Area, thus emf is directly proportional to area. And hence, larger kVA rating of transformer require larger area....

I need this transformer to build extremely powerful RF antenna for causing disruptive effect on magnetosphere 😂

More the voltage ratinh more will be the turns ratio. Hence bigger stator structure required to fit in the windings.

Hmmm might be enough to get me out of bed in the morning

If you touch that thing even your soul would be pulverized.

Increase in voltage leads to increase in windings , insulation, structure etc hence increase in overall size of the transformer body.

We know that voltage equation of T/F is= 4.44NBAF,Where N-no.of turns per phase B-maximum flux density A-net cross sectional area of core,(i,e)Gross cross sectional area*window factor(Height window/width of window) f-Rated flux From above equation it is clear that,more the voltage1) More the number of turns..2)cross sectional area of core is more ,to get rated flux.. KVA=1.732*V*I---> the current is more on lv side, requires large conductor area..HV side requires large amount of insulation than lv side.. Temperature rise affects the amount insulation & amount of coolent required.. Therefore from above all it is concluded that,as voltage rating increases,Size of T/f increases to accommodate all these requirements.

a transformers size is based on authority- that's why optimus prime is big, and megatron too. the other transformers are all smaller, even as small as a radio.

Since voltage ratio of a transformer is directly proportional to the turn ratio so, more the voltage handling capacity more will be the number of turns and more the number of turns more the insulation will be needed due to which both size and weight of transformer increases .

In transformer, as the voltage rises the no of turns will increase in order to produce higher voltage comparatively. Thus,we need higher rating of auxiliaries of transformer. Apart from that, voltage is directly proportional to insulation to prevent from abnormalities and faults.so, it will also increase the size of transformer

The higher the voltage the more turns on the winding. In order to compinsate for induction. Most likely the flux material that is a componate of the primary and secondary winding differ in thickness and surface area which effects the overall size of the transformer.

What kind of primary overcurrent protection are they working with? Also, what’s the impedance? I’d be curious to see the specs

The transformer size increases depends on the rated voltage because as the voltage increases the insulation is also to be increased .that's why transformer size increases with its rated voltage

The size is related with the KVa. Increasing the KVA reduce the losses in the grid and the cost of the transmission line or Increase the capacity of the TL.

Proud to be big well done seimans.
