Power Factor Correction
The power factor of a load is defined as the ratio of active power to apparent power, i.e. kW divided by kVA and in mathematical terms is referred to as cos Ø. The closer cos Ø is to unity, the less reactive power is drawn from the supply. Power Factor (cos Ø) = Active Power (kW) / Apparent Power (kVA).
Power Factor correction are a technique to compensate for poor power factor and thereby optimise the transfer of useful power into electrical equipment.
