WHY INSTALL A POWER FACTOR CORRECTION SYSTEM

A power factor correction system improves your electrical system in such a way that electrical energy is more efficiently consumed. From a customer’s perspective, improving the power factor of an electrical system implies reducing losses due to the inductive reactive components in the circuit and of course, reducing utility bills due to the extra charges paid upon low power factor.

 

HOW DOES THE POWER FACTOR CORRECTOR WORK?

It is possible to produce reactive energy, where necessary, by installing power capacitors necessary for automatic power factor correction systems. Capacitors absorb a current that is 180% out of phase with the inductive reactive current; the two currents are algebraically summed together so that circulating upstream from the point of installation of the capacitor is a reactive current that is equal to the difference between the inductive and capacitive currents.

The exchange occurs between the capacitor and user; this is why we say that the capacitor supplies reactive energy to the user.

 (By so doing, it improves a low power factor to to high power factor and prevents the user from paying penalty charges to the utility company).                                        

HOW CAN A COMPANY SAVE MONEY BY INSTALLING A POWER FACTOR CORRECTION SYSTEM? 

 CEB encourages the end user to improve the  power factor of their electrical system because high power factor contributes to higher demand in KVA. High KVA over CEB network requires more power stations to come in, whose running costs are higher.

This is why CEB makes the effort of measuring maximum demand in tariffs applicable to commercial and industrial consumers. It has defined maximum demand as the highest average KVA recorded during half hour periods over the six months preceding the date of meter reading.

It  charges commercial consumers at the rate of Rs 186 per maximum demand KVA per month and industrial consumers at the rate of Rs 144 per maximum demand KVA per month.

 

CEB  also measures average power factor as KWH/KVAH , both quantities being measured over the month. If the power factor  is  lower than 0.9, CEB charges Rs 65 for every actual demand KVA in excess of demand applicable if power factor had been 0.9 in the month.

CEB will reset the maximum demand account  of its client to zero , if the latter  installs  a new  power factor correction capacitor bank. It will  also  reset account , when its client needs to repair a defective power factor correction capacitor bank.
