How to determine the required capacity KVA for a three-phase transformer?
KVA=V*I*1.732/1000
V=Voltage(V)
I=Current(A)

Transformer Knowledge
How we definite transformers
Transformers are static equipment used for transferring power from one circuit to another, the frequency could be 50HZ or 60 HZ, this is a very basic definition of transformers. There is no rotating or moving part, so a transformer is a static device. Transformer operates on an ac supply and work on mutual induction principles.
