Power Factor Correction

Our Power Factor Correction Solutions

Our power factor correction equipment and subject expertise have provided stability, current reduction and volumetric support to some of the most complex and simplistic applications in power.

The payback period on investing in power factor correction is typically 12 to 24 months.

Unlike other companies, we take our time to analyse meter data, your site’s conditions, and the costs and benefits of solutions for both high and low-voltage systems. We don’t rely on a five-minute snapshot of your energy usage.

This means we can install the correct power factor correction equipment and ensure the voltages at the mains are as efficient as they can be. This results in no harmonic generation issues and superior performance.

Our power quality engineers can provide you with the following:

Power Factor Correction Equipment

Taking steps to address a low power factor with the latest equipment such as PFC capacitors can see a huge increase is power factor efficiency. Installing capacitors across the main power supply is the simplest solution but often some machines are far more complex. This may require specialists such as ourselves to design specific equipment for the machine.

It’s important to note that power factor correction equipment does have a lifespan and may not operate as it used to when first installed (i.e. over 20 years ago). On top of this, the layout may have changed and you should resurvey the site to check for poor power factor and decide whether the equipment needs an overhaul.

Benefits of using the latest PFC equipment include:

Once our team installs and supplies a power factor correction unit, it will continue to work for many years to come. The savings from the reactive power charges will reduce and the capacitors will pay for themselves. All of the capacitors that we use are manufactured in house and we are able to provide maintenance, repair, technical support and 24 hour disaster recovery solutions.

Please feel free to contact one of our experts to talk about the bespoke solutions we can provide for the specific needs of your business. We are UK manufacturers of power factor correction capacitors with a large client base that not only spans nationwide but also across seas.

Power Factor Correction (PFC) is the relationship between an electricity distribution network’s ‘active’ and ‘reactive’ power. It measures whether the system voltage and current are in phase and efficient. It also provides a volume of stability connected in parallel to your power supply or load.

It is measured in a figure starting from 0 to 1, with the higher value being the more efficient of the two. Electrical power systems with a power factor of 0.95 and above are deemed very efficient.

If a network is 100% efficient and has no reactive power, its Power Factor is 1 (also known as unity). This is the optimum for power transmission but is practically impossible to attain.

Power factor correction is a key issue for the UK industry that impacts energy efficiency and electricity bills. The reliability and availability of equipment and network infrastructure are just as important.

Different types of electrical devices cause variations in the power factor readings or a poor rating. These include AC motors, arc welders, fluorescent lighting, and air conditioning connected to the grid that consume or generate reactive power. Unless the variations are corrected, higher currents are drawn, leading to grid instability, higher costs, and reduced capacity.

Poor power factor can have several significant consequences for both electrical systems and their operators. Some of the negatives include:

  • Higher energy costs due to inefficient power use
  • Reduced capacity as the system’s components handle less load
  • As there is an increased current flow, it can cause equipment to overheat
  • Voltage drops, causing equipment inefficiency and malfunctions
  • Further power quality issues that can affect the performance of sensitive electronics
  • Reduced system efficiency

Power factor correction methods include using capacitors, synchronous condensers, phase advancers, active PFC devices, passive components, variable frequency drives, and harmonic filters. By adjusting the power factor to optimal levels, these methods reduce reactive power, improve system efficiency, and lower energy costs.

Power factor correction benefits your business by reducing energy costs, improving system efficiency, and increasing the capacity of your electrical infrastructure. It minimizes heat losses, prevents equipment overheating, and enhances voltage stability, leading to fewer malfunctions and a longer lifespan for your equipment. Additionally, it can help avoid regulatory penalties from utility companies, ensuring smoother and more cost-effective operations.
