why transformer ratings in kva?
Answer Posted / m. jamshed
As transformers are the power source and every power source
is deigned for specifid value of current and voltage.
The amount of current in A/C circuits is greatly affected
by p.f.as if we take two examples for the same kw with
different p.f we will get different amount of current that
is high current for low p.f and vice versa.
For the transformers we do not know about the load p.f,so
it will be rated in kva to determined the exact value of
current it can provide.
