What is Power Factor?

Power Factor is a measure of how effectively your equipment is using electricity. It's calculated as the ratio of real power to total power and is expressed as a numerical value between 0 and 1.0. A good power factor (0.98-0.99) means your equipment is using energy efficiently, while a low Power Factor (anything below 0.98) means you're wasting energy.


If your power factor is 0.7, you’re using - and being charged for - 30% more power than you should be. The closer your power factor is to 1, the more efficiently the business is consuming electricity.


Inefficient electrical systems use a large quantity of ‘reactive’ power (kVAr), representing the power lost in the operation of inductive equipment such as transformers. This invariably increases the total power load, also known as apparent power (kVA), and reduces your overall power factor. 

Why is Power Factor Correction Equipment Important?

A low power factor means you're drawing more current than you need, resulting in higher capital expenditure and operating costs, such as increased demand charges, as you're paying for extra power that's not being used.


Running motors, machinery, and other equipment uses a lot of power. The electricity needed to keep things running is referred to as active power or real power. It is measured in kilowatts (kW) on your electricity bill.


Traditional electrical equipment, such as motors and transformers, can lead to high energy losses and reduce the overall efficiency of the system. These losses can manifest as heat, vibration, and noise, which can lead to premature wear and tear on the equipment. Conventional equipment may also require more frequent maintenance, as it is more prone to overheating and mechanical failure.


Our power factor correction (PFC) equipment can help you improve your power factor, decrease wear and tear on your equipment, reduce your energy usage, and lower your electricity bills.


The Australian Energy Regulator allows electricity providers to penalise businesses for extra demand on the electricity grid. If your most recent power bill has a charge for kVA (kilo-volt-ampere), then your power factor is probably inflating your bill.

How Does Power Factor Correction Work?

PFC equipment compensates for reactive power and improves the ratio of real power to total power. This is achieved by installing capacitor modules with reactors and a controller that acts as a buffer between the incoming power supply and the main distribution panel.

FAQs about Power Factor Correction

Quality Energy is here to answer your queries. If your question is not listed below, please do not hesitate to contact our team, we would be happy to assist.


  • Are the Power Factor Correction Units tested prior to delivery?

    Yes. Quality Energy conducts extensive Factory Acceptance Testing (FAT) to Quality Energy’s standard test sheets, or customised to the clients' testing regime. Clients are encouraged to witness the FAT in our Melbourne facility to ensure a smooth handover.

  • Does Quality Energy use ISO9001 quality-controlled electrical components?

    Yes. All electrical, mechanical, and electronic components and equipment are sourced from quality accredited suppliers.


  • What level of compliance standards does Quality Energy adhere to?

    Quality Energy's power factor units are compliant with the following standards:


    • AS31000, 
    • AS/NZS 61000,
    • AS 1306,
    • AS 2067,
    • AS1033,
    • AS1028,
    • IEC 60871,
    • AS 62271,
    • AS 1864-1976,
    • AS C135-1954

  • What causes poor Power Factor?

    The leading cause of low Power Factor is inductive loads such as electric motors, ballast lighting and transformers. In addition, inductive loads that are not used at, or near, their design capacity contribute significantly to a low Power Factor.


  • What is Reactive Power?

    Reactive power is considered wasted power as it does not perform useful work in a system. The higher the reactive power, the lower the power factor. Reactive power puts additional demand on the electricity network and inflates your power charges. This is represented on a power bill as 'kVA Demand'.


  • How much can I save by installing a Power Factor Correction Unit?

    Power Factor Correction provides many benefits such as reduced electricity utility bills, increased system capacity, improved voltage and reduced losses.

  • Testimonial from Rupe Virk, Head of Projects Jalplas

    In early 2020 our site in Thomastown was experiencing power quality issues that was affecting our critical manufacturing equipment. After contacting Quality Energy and having them conduct a Power Quality study, it was determined we required a 200A Active Harmonic Filter to help eliminate our harmonic pollution and protect our entire infostructure. Quality Energy designed, installed and now maintain our Active Harmonic Filter and we have had a clean bill of health since the installation took place.

  • Testimonial from Chris James, Kurv Living

    In June 2020, Kurv Living were faced with several power outages due to the quality of the power entering our manufacturing facility. After completing extensive Power Quality diagnostics, Quality Energy determined that we had high harmonic levels that were causing our critical machinery to shut down. Quality Energy then installed a 200Amp Active Harmonic Filter in September of the same year and we haven’t had any issues since.
