How do we do selection of transformer with a given specific load

First, what is the input voltage and the desired output voltage? Is the output voltage fixed, or do you need a range of adjustment (taps)? Do you need isolation between the input and the output? If not, an autotransformer (single winding) might be acceptable. What is the frequency, and is it single phase, three phase Y, or three phase delta?
Next, what is the power rating? Small transformers are usually rated in output current, whereas larger transformers are rated in KVA. This is the maximum load; a smaller load would not be a problem.
Finally, what are the mechanical factors? Does it need to be hermetic or can it be open frame? Do you want terminals or wire leads? What shape and size? What is the mounting?
It's not really that hard. Usually you can browse through a catalog and find the transformer you need in minutes.

First..... decide which step up or step down transformer you want it to be... maybe 33kv/11kv or 11kv/433V... and so on.
From there, find the KVA of the transformer you need.. maybe 1500?? or 2000 KVA
Next... decide it whether a hermetically sealed or tap changes type or so on and forth.
good luck

Voltage,and amperage, or kva's power required in wattage.
