In the ideal conditions the power of the load is equal to
its KVA , but practically a phase difference will happen
between the volt and the current and it will lead to reduce
the KVA to the KW , the ratio between the KW power (Actual
power ) & the KVA (Appearent power) is the power factor .
In my opinion we can say the KVA is the theoritical value
of the power , and it can be equal to the Kw if no phase
difference happened.
The simple way is kw=kva*power factor.
