Power Factor Correction

Power Factor Correction

If your site has a poor power factor, you could be paying for energy that cannot be used.

Power Factor is the relationship between working power or real power (kW) and reactive power (kVAR).

Most loads are inductive, and therefore require an electromagnet field to operate. Real power & reactive power are the 2 kinds of power required for this to happen. Real power performs the actual work in creating (heat, light, & mechanical motion and other services), while the reactive power maintains the electromagnetic field.

These two combined create apparent power. Apparent power is measured in kVA. If your site has a poor power factor, you could be paying for energy that cannot be used.
Power Factor Correction decreases the gap between the kVA and kW’s needed at a site. You will see this as network charges in kVA on your bill. Information and layout will vary between energy retailers.

The greater the gap between kVA & kW’s, the greater the demand charges will be. The smaller the gap, the lower demand charges. The higher the Power Factor, the more effectively electrical power is being utilised, conversely the lower the Power Factor, the more inefficient your consumption is. The installation of Power Factor Correction introduces an alternative and more efficient source of reactive power.

This decreases the site requirement for reactive power from the electrical power system and therefore reduces kVA demand.

Benefits of ABB Power Factor Correction can include:

  • Reduced cost: Reduction in kVA demand and therefore electricity costs. This will be ongoing savings for the life of the equipment
  • Equipment life: Extend the life of your current equipment on site.
  • Compliance: Compliance with regulatory codes.
  • Expansion: More power available for site expansion without the need for upgrading the sites Transformer/s, Switchboards and cable.
  • Payback period: usually 1-3 years


The Installation process

Once a Purchase Order has been received from you, all relevant documentation is sent down to our factory for the manufacture of your PFC unit.

This process will take approximately 3-4 weeks. You will be notified by email from our office with an ex-works delivery date. The unit will then be shipped up from our factory direct to your site. We will liaise with yourself or a site supervisor to meet on site before arrival of the unit so as to place into agreed position and the preliminary work prior to the shutdown of the MSB. If you have any site inductions that need to be completed before the installation, please notify in advance. If you require any other forms of paperwork for the installation, please also notify in advance.

After all documentation has been finalised, we will then work in with yourself as to a time and day suitable to you for the final install procedure.

This is typically 2-6 hours. Depending on what work is required at the MSB. After power has been restored to the MSB, all is checked and tested and the PFC unit is commissioned. You will then receive by email a full commissioning report.


All HTC PFC units come with a 5 year warranty on all parts if the unit is serviced yearly by a certified technician. HTC can offer this as part of the initial unit purchase or can be taken up within 12 months of the date of purchase. This will give you peace of mind for the next 5 years as HTC will look after the service & maintenance on an annual basis at no extra charge to you. A service/maintenance schedule will be sent to you after the final commissioning of the unit which will detail approximate days in the month for each scheduled service, 12 months from completion.
