Get Why Transformer Rating In Kva Pictures
Get Why Transformer Rating In Kva Pictures. Why transformer is measured in kva? In other words, it can only step up or step down the value of current and voltage while the power and frequency would remain same.
Jul 20, 2021 · in other words the total losses of a transformer are depending upon the voltage and current ratings of the transformer.
And that’s the reason why transformers are rated in va/kva/mva. To give the rating in kw, along with voltage and current we need one more thing which is power factor of the load. Transformer always rated in kva instead of kw as the name suggest, transformer only transfer the power from one circuit to another without changing the value of power and frequency. It is our turn to transform and utilize the 11kva as 11kw (we can do it by improving the power factor to 1 in case of pure resistive load ) which is not predictable and even very hard to get in case of inductive and capacitive loads where power factor would have different values.
