12+ Why Transformer Rating In Kva Quora UK

12+ Why Transformer Rating In Kva Quora UK. Kva rating, in simple terms just gives the transformers' load carrying capacity. Transformer is rated in kva because the power factor is not considered during manufacturing.

Why Is A Transformer Rated In Kva Quora from qph.fs.quoracdn.net

Hi transformer rating is always show in kva due to power factor. It is a combination of real power and reactive power. And hence, it has to transform total power i.e.

So if the rating of a transformer is 50 kva then at normal power factor 0.8, the output power will be 40 kw.

The power is maintained constant throughout the machine. Just because a transformer steps up or steps down voltage doesn't mean that it's kva rating changes. These losses are dissipated as heat, and they heat up the transformer. Copper loss of a transformer depends upons currents and iron loss voltage.
