Power Factor Correction - New Technology.  
Power factor correction has energy saving benefits in cases where a large electric motor is driving a heavy load.  Investigated under the assumption of using a fractional-order capacitor. The effects of the fractional order of the capacitor on real and reactive source power, as well as on the value of the correcting capacitance are analyzed. you should call us first.
Q. Under what circumstances are capacitor corrections warranted?
 A. Despite the slight energy savings, correcting power factor can bring significant savings in energy bills when the utility imposes a low power factor penalty in their rate structure, as most utilities do for industrial customers. The simplest penalty is imposed through basing demand charges on kVA instead of measured kW. Another penalty approach is to calculate a billable monthly demand charge that is equal to the measured demand times the ratio of the desired power factor (often 95%) divided by the measured power factor.


How much you can save through installing capacitors depends upon your initial power factor, the level you correct to, motor horsepower rating and loading, and how the penalty charge is calculated by the utility.

Utilities charge for reactive power in a countless number of ways. Some utilities charge for kvar demand, while others charge a strait fee for a power factor less than their target. To fully understand the benefits of NEPSI's shunt capacitor and harmonic filters, you must acquire your electric billing rate structure. This rate structure will describe how cost for poor power factor are added to your monthly bills. If you need assistance in calculating your pay-back periods, feel free to contact our nearest factory trained sales representatives or just call Northeast Power Systems, Inc.

Table 1, which contains kilowatt multipliers, can be used to calculate the amount of kvar required to raise your "original power factor" to your "desired power factor". For example, a facility has a peak kilowatt demand of 5000 kW with a power factor of 0.80. The facilities engineer wants to raise its power factor from 0.80 to 0.95. The kW multiplier obtained from table 1 is 0.421. Multiplying this value times the facilities kilowatt demand yields 2105 kvar (0.421 X 5000 = 2105). Therefore, a 2105 kvar capacitor bank would raise the facility's power factor from 0.80 to 0.95.
