How to calculate the Kilovolt-Ampere (kVA) Rating of a Transformer

Learn about the kVA rating of a transformer and what it actually means in terms of power and learn how to calculate the kVA rating using a simple formula.

Thanks for the video!

The kva rating of a transformer has to do with the power factor, not the copper and core losses within the transformer. A power factor less than 1.0 means that reactive current is present, so the transformer will be drawing and supplying more current than would be that of the total resistive load, and the copper and core losses in the transformer. Transformer losses are resistive in nature, dissipating in the form of heat, so loss current is in phase with the voltage delivered to the load.
An ideal transformer/network/load system will have equal kva and power ratings. Real world transformers will need ratings for Kva and Kw that are different to accommodate anticipated reactive networks and loads.

2.3kva 🤷

Is also similar for that of 3-phase one?
