why we r used APFC Panel in industrial area.when P.F. low
then wat will be the effect in our system?

Answer Posted / umashankar

The ideal Power Factor (PF) is Unity or 1, but most
Industrial loads have a PF lower than 1. Moreover, this
lower PF is usually due to Inductive loads, arising out of
the windings of Transformers, Motors,etc. These loads
consume kVARs (the Wattless component) from the supply
line. The APFC supplies these kVARs via a capacitor located
close to the load, reducing the current drawn from the
supply line. For an Industry with dynamically changing
loads, Automatic PF Compensation affords the best Return on
Investment, since the kVAR investment required is smaller
than with fixed capacitors needed to meet the entire load.
