why the rating of transformer in only KVA not in others?
Answer Posted / prakash
1.Power factor of the load in not defined in case of
transformer, so it is not possible to rate transformer in KW.
2. The losses (Copper loss and current loss) of the
transformer depends on current and voltage not on load.
3. Transformer is not a load and having no effect on PF and
its only transfer the constant power from one voltage level
to another voltage level without changing frequency.
