Dating back to the 19th century, Power Factor Correction is based on proven scientific concepts concerning Active power, Apparent Power and Reactive Power. PF or Power Factor describes how efficient electrical equipment converts current into output by looking at the ratio of Active power to Apparent Power.
- Active power is referred to as working or true power measured in watts or kilowatts (W or KW) and is the power drawn by an electrical circuit.
- Apparent power is measured in volt-amperes or kilo volt-amperes (VA or KVA) and is calculated by the voltage multiplied by the current that passes through an electrical circuit.
- Reactive power is referred to the power drawn by an electrical installation to create magnetic fields (such as motors, transformers and ballasts), and is responsible for increasing the amount of apparent power drawn by an electrical installation.
- Increasing the Reactive power causes Power Factor (PF) to decrease.
- Power Factor correction ensures that plant electrical equipment effectively converts electrical currents supplied by your power utility.
- PF correction, when applied correctly can reduce your organisations utility expenses.
- Allowing for additional power loads, Power Factor correction can increase commercial systems capacity.
- Power Factor correction is responsible for a reduction in transmission losses.
- Through improved production efficiencies, PF Correction can have an indirect impact of positive profit margins and improved competitiveness.
