POWER FACTOR CORRECTION APPARATUS AND METHOD OF PRODUCING A POWER FACTOR CORRECTION CAPACITANCE FOR A SPECIFIED LOAD

摘要

An apparatus (10) for determining the necessary capacitance required to correct power factor in an electrical power system (1) comprises a plurality of capacitors (20) having predetermined capacitances connected in series with a plurality of switching devices (30) , said capacitances (20) and switching devices (30) connected between the line voltages of said power system (1) to correct power factor. A means for determining power factor in said power system may include a power factor meter or a plurality of current transmitters (70) and voltage probes (80) used to provide data to a microcontroller (40) to calculate power factor.
