the capacity of your electrical system:
Assume you have a load of 100 KVA. If your existing power
factor is .80, then you have enough power to light eight hundred
100-watt light bulbs. If you improve your power factor to .95,
then you will have enough power to light nine hundred and fifty
100-watt light bulbs. Figure 2 shows the effect that power factor
improvement has on a power triangle.
Improving your power factor can save you money:
No matter how your utility bills for electric consumption, you can
save money by installing power factor correction capacitors,
because you will use less energy, lengthen the life of your existing
equipment and reduce electrical requirements for any new or
future equipment that you install.
KVA Billing
If your utility uses KVA billing, you are charged for the current
you draw from the grid. By improving your power factor rating,
you will pull less current. Your charges will be lower, to more
closely align with the actual amount of power you are using.
