Power Factor Correction Calc

All of we know that low power factor is not a good for electrical system because of adverse kind of losses. right
Through power factor correction app, after put all data like
Active power in KW
Existing power factor
required power factor and
supply voltage in KV

We find
Existing system conditions
Active power factor in KW
Reactive power in KVAr
Apparent power in KVA
Current in A with
Improvement in system conditions and how much reduction in losses.
