Benefits
There are many advantages to maintain a high power factor, below are two:
REDUCE I2R LOSSES A potential savings in billed KW-Hrs can be realized depending upon where the capacitors are located in your electrical system. When capacitors are energized they reduce the total power usage (KVA) from their location in the system up to the utility source. In other words, capacitors reduce the current in amperes that had been flowing from the utility to the capacitor location. This ampere reduction might be as high as 20%. Since watt loss generated by current passing through a conductor is expressed by the formula ... watt loss = (Ampere) 2 x Conductor Resistance (W=I2R) ... it is obvious that locating the capacitors at the extremities of the feeders and branch circuits (where the loads are) can result in a sizeable reduction in total KW-Hrs usage every month.
ELIMINATE POWER FACTOR PENALTY A high power factor eliminates penalty dollars imposed when operating with a low power factor. For many years, most utilities demanded a minimum of 85% power factor as an average for each monthly billing. Now many of these same utilities are demanding 95%...or else pay a penalty!
The actual wording or formula in the utility rate contract might spell out the required power factor, or it might refer to KVA billing, or it might refer to KW demand billing with power factor adjustment multipliers. Have your utility representative explain the particular rate contract used in your monthly bill. This will insure you are taking the proper steps to obtain maximum dollar savings by maintaining a proper power factor.
