Power Transformer

some of the largest size dry type transformers available today are 500kva,750kva,1000kva,1500kva,2000kva,2500kva,3000kva,37500kva,5000kva and 7500kva

To ask a question like 3↑ is really silly - how on earth would you expect a bunch of strangers to know your organisation's power transformer selection criteria and purchasing procedures?

Obviously the biggest problem with any transformer is getting rid of the heat. Space and the available cooling would be two deciding factors for not using them.

i) I have read from manufacturers' catalogues that dry type transformers are available upto 33kV, 10MVA Capacity too.

ii) Yes! Very much! Dry Type transformers are power transformers too!

iii) Higher kVA obvioulsy means higher voltage rating. At present days technology, insulation is still a problem with dry type transformers at higher voltages.

dear expert,

kindly send the catalogue with you have it will be helpful to me, i searched in internet i also got 10000kVA availability but i am not able to get exact answer.

Thanks in advance

If you were born to engineer, you would know the answers to your questions!

At last you should read, One of the Electrical engineer to become best. If you know post the answers.

Thanks in advance,

Why you didn't ask "how many types of dry type trnsformers are available,insulations used,winding materials used",advantages/disadvantages over oil filled types and so on?

If you are interested to answer please do. Dont hurt or insult if someone not knowing the answer they will do you you did here. Dont insult.

1. Maximum kVA rating is depends on the production capacity of Manufacturing firm.

2.Normally one transformer is not installed under another transformer.

3.we dont know, why you are not choosing it.
