Hi

We know that, Transformer always rated in kVA.  Below are the two simple formulas to find the rating of Single phase and Three phase Transformers.

Find Rating of Single Phase Transformer

Rating of Single Phase Transformer:

P = V x I.

Rating of a single phase transformer in kVA

kVA= (V x I) / 1000

Rating of a Three Phase Transformer

Rating of a Three Phase Transformer:

P = √3. V x I

Rating of a Three phase transformer in kVA

kVA = (√3. V x I) /1000
