Power factor is the ration between the KW and the KVA drawn by an
electrical load where the KW is the actual load power and the KVA is the
apparent load power. It is a measure of how effectively the current is
being converted into useful work output and more particularly is a good
indicator of the effect of the load current on the efficiency of the
supply system.
Power factor correction is achieved by the addition of
capacitors in parallel with the connected motor circuits and can be
applied at the starter, or applied at the switchboard or distribution
panel. The resulting capacitive current is leading current and is used
to cancel the lagging inductive current flowing from the supply.
The use of Power Factor Correction Equipment reduces the
amount of electrical current consumed by industrial and commercial
consumers. This in turn reduces the distribution system losses leading
to improved efficiency, cooler equipment operation, increased capacity
of your existing supply system, longer equipment life and may result in
lower electricity bills from your supply company.
