Transformer inductance & resistance
Transformer inductance & resistance
(OP)
Is there a rule of thumb as to figuring out what the inductance and resistance should be in a transformer for a given power rating [kVA or MVA], turns ratio, and may be voltages?
I heard there is this 5% or 10% rule. I am putting together a model but Manufacturers don't usually give you the specs on inductance and resistances.

RE: Transformer inductance & resistance
The IEEE Red Book has typical values of impedance and X/R for various types and sizes of transformers - that would be a good starting point.
But no, there is no one-size fits all method to estimate transformer impedance based only on the kVA rating.
Hope that helps.
