What is Power Factor Correction?

Power Factor Correction Equipment from PQE


There are many different types of electrical equipment which affect the electricity supply in different ways. Some electrical loads have a bad power factor, which results in higher electrical current flowing than is necessary to achieve the end result, irrespective of whether that is heating, lighting, mechanical power, ventilation, etc
This means more generators and a heavier distribution network is required, the results of which is YOU the user have to pay for it all
Power Factor can be regarded as a measure of “efficiency and has values ranging from 0 to 1, where 1 is 100% efficient
Power Factor Correction equipment improves this “efficiency” so that less electrical current is needed to achieve the same result. A wide variety of products are available to do this, some of which operate automatically, in order to compensate for varying electrical loads which are common in today’s manufacturing plants and offices

What does Power Factor Correction do?

  • Reduces load in Cables and Switchgear, results in extension of their useful life and improves system reliability
  • Increase the useful load from a given transformer. For example, a 1MVA transformer at 0.75 PF can only supply 750KW of load. Increasing to 0.95PF can give extra 200KW of load
  • Reduces current flow and power loss in cables and transformers, etc
  • Reduces Levied Charges. Using above example, 200KVA saving in chargeable load saves £300 per month on typical charge of £1.50 per KVA of maximum demand charge for supply
  • Reduces PF charges, & Climate Levy charges
  • Reduces the number of KWH units consumed

How much will it save?

PQE will be pleased to advise on your requirement and explain the benefits and cost savings which result. This can usually be done quickly, often a copy of two or three of your electricity bills is sufficient for us to determine your requirements

Why your company should install Power Factor Correction?

Most large consumers have dedicated incoming mains transformers. When these are fully loaded, site power usage can not be increased unless the rating of the transformer is increased. If your power factor is poor, improving it will free up capacity, which is available for business expansion
Using power factor correction equipment to do this will save many thousands of pounds, when compared to the cost of installing a new transformer – up to 80% less. In addition the equipment can be installed easily, quickly and without the need for a supply power down of several days
If you need Power Factor Correction, the sooner it is installed, the sooner you will save money. Interest-free government loans are available for this type . If you feel that you may need Power Factor Correction, contact us now - our advice is free
