Power factor is imp bcoz....ex: If we have an panel that
will give the o/p of 300KW but if we dont maintain the
powerfactor by using APFCR it will give the o/p of 240KW
only....by maintain the powerfactor by using the APFCR we
can get (0.98%)....power factor means something lagging and
leading in power due to harmonics...
