POWER CAPACITORS
POWER CAPACITORS135. Power capacitors are capacitors with relatively large values of capacitance which are used on power-distribution systems or in industrial plants for improving the power factor. Since many power companies include low–power-factor penalties, kilovolt-ampere demand rates, or power-factor bonuses in their rate schedules, it is often economical for industrial consumers to install capacitors for power-factor improvement. These capacitors are connected across the line and neutralize the effect of lagging power-factor loads, thus reducing the current for a given kilowatt load. The amount of reactive kilovolt-amperes of capacitors required to raise the power factor to any given value can easily be determined from the chart of
