A device’s power factor represents how effectively that device is using the power that is being supplied to it – in other words, the power that you are paying to use.

It is a measure of electrical efficiency, and in electrical engineering terms, is defined as the ratio of a circuit’s “real power” to its “apparent power”. Devices with high power factors make better use of the power being supplied to them than devices with low power factors. In this context, a power factor can range from 0 to 1, where 1 represents 100% efficiency, in which case a device would be using all of the power it is being supplied with.

In short, having a low power factor means that you are not getting your money’s worth when it comes to the electricity you buy from the power company. Operators of commercial buildings and data centres will often employ power factor correction (PFC) units, which can improve their power factor, and drive down their electricity costs.

PFC can:

  • Increase power use efficiency
  • Reduce your power bills
  • Filter unwanted frequency harmonics
  • Reduce stress on your electrical equipment

PFC units can experience failures, however, and it’s not always obvious when they are not functioning correctly. These PFC units need regular maintenance, to make sure they are increasing power factor as intended.

We offer PFC maintenance services to ensure that your PFC unit is operating as it should, and recommend 6-monthly and annual services to diagnose and fix problems. This preventative maintenance ensures your energy bill is kept to a minimum and your PFC unit is efficient and effective.
