capacitor banks are highly used in substations for
increasing the power factor. depends upon the load type
highly used by the consumer its value is to be selected.But
most of the loads are inductive in nature.So the power
factor will be lagging in nature.In order to increase the
power factor upto unity level the capacitor banks are
used.But during midnight time the power consumed by the
consumer are very low.At the time we require low capacitor
bank values.It can be explained by the following
equations.we know that
C=Q/V and P=(3)1/2 VIcosO
As phase angle between the voltage and current increases in
the leading side means the power factor will be increased.
