World's Largest Power Transformer 2

[mutimuti]

Can anyone tell me what is the MVA of the world's largest transformer, how many tons with oil and who makes it?

 

[dede61]

The biggest one I came accros up to now is 1400MVA PST

 

[bluemagic]

In China,the largest one is 1200MVA transformer includes 3 units of 400MVA/500kV single phase auto power transformers.
Manufactured by ABB.

Are any link to pictures of this monster?

It may be like this in theory and practice, but in real life it is completely different.

I would also like to take a look at the pictures of this and similar transformers.

Areva have built singles up to 1100MVA and banked three phase groups to 1650MVA. I'm struggling to find any photos though!

Some where I had a picture of a 2200 mVA transformer. I think it was for a pplower plant in NYC. Heres a couple.

If you seach google images for "transformer schnable cars" there are some pictures of big transformers.

Hyundai claims 15,000 MVA.

This one is the Fortress maximus, it's 2-1/2 feet tall.

 

[alehman]

That's a really big Transformer.

The HHI transformer website says 15,000 MVA production facility, not a single 15,000 MVA transformer

 

[ScottyUK]

Hyundai Heavy Industries (HHI) established production facility for world’s largest transformer with a 15,000 MVA capacity. The facility has the world’s largest production capacity with 60,000MVA in a single plant, which is similar to the total amount of Korean power plant’s capacity of 65,000MVA.

No it doesn't. Read it carefully.

Regardless of what the website says I don't really think a 15 GVA transformer is likely to exist, but I do wonder if the translation has gone askew or if an extra '0' was inadvertently added. If it really did exist and was built using conventional technology it would have a throughput of roughly one quarter of the UK's generation capacity, be the size of an apartment block and weigh many thousands of tonnes. At 400kV the line currents would be over 20kA.

It does explain where all the copper and silicon steel has been going though.

I can't imagine an application for a 15,000 MVA transformer and have to think it is in error. But the statement seems very clear.

 

[bacon4life]

The translation is in error. This link says more clearly that they have just opened a new production line, and they now have an annual total capacity of 60,000MVA.

how would you move a 15,000 MVA Transformer? Probably weight about 7 or 800 tons.

 

[ScottyUK]

Hi BJC,

Our 400MVA GSU transfomers weigh in at around 300 tonnes filled: I think your estimate is a little on the light side, even if it was an autotransformer.

Do you do translation work for Hyundai?

JRAEF,
Maybe you could send photos after applying 400kv?

When we talk of largest transformer in the world,MVA alone will not give the size.In case of auto-transformers used for interconnecting two grids,equivalent two winding MVa rating will be much low ie it will be much lighter than a two winding trf of same MVA.When the size of unit goes too big to handle,engineers plan for three single phase units to form a three phase bank.But from electrical angle (current to handle and leakage flux to manage)size is decided by the three phase bank rating.
A three phase bank will be 30-40% costlier than a three phase transformer.But due to strategic reasons and transportation limitations,many times three phase bank is preferred.Largest rail wagon available today for transporting the heaviest transformer package is about 500 tonnes and in other cases transport is done through water paths or special road trailers

Largest three phase units made so far is 1630 MVA 400 kv phase shifting transformer made by ABB,Germany in 2003 for Italy( weight 820 tonnes,losses 2.6MW)and 1400 MVA (ABB ) made in 2004 for Belgium.( weight 1300 Tonnes,LBH 36*18*5 metres ) Probably the largest 3 phase unit size will be around 2000 MVA required for 1600-1800 MW nuclear power units being planned in some countries.

When 3 phase banks are considered,largest units made so far are 3000MVA 1050 KV Auto made by Japanese manufatueres in 90's, 2250 MVA 765 kV made by ABB Canada for AEP USA (2003), 3600 MVA 735 kV made by ABB ,Canada and 1980 MVA 500kV HV DC converter transformers made by ABB,Sweden for Sylmar( Pacific Intertie-Weight of single phase unit 550 Tonnes,weight of heaviest package 355 Tonnes)Maximum bank size required in near future may be 4000 MVA Auto required for interconnection of very large grids.

Weight of transformers vary approximately to the power of 0.75 ie if the weight of a 100 MVA unit is W tonnes,then weight of 200 MVA will be 1.7 W tonnes.So it can be seen how impossible to make a 15 000MVA unit from technical and logistical angles.From strategic considerations also no one will plan for such a size.
