What Is Power Factor Correction?


For those who need to get up to speed with this useful technology, here's a brief overview of what it's all about:

PFC is a technique that enhances the efficiency of electrical systems. It involves adjusting the power factor of a system to bring it closer to unity* (1.0). This correction minimises wasted energy, reduces costs, and optimises electrical power, making it an essential solution for businesses in Headstone South relying on electrical machinery and equipment. By improving the alignment of voltage and current waveforms, PFC ensures that your electrical system operates at its most efficient, ultimately leading to energy and cost savings.

Power factor correction works well in tandem with voltage optimisation but they are different services to each other we covered in our article “what is the difference between voltage optimisation and power factor correction?”.

How Does Power Factor Correction Equipment Work

How Does Power Factor Correction Equipment Work?


Most PFC equipment is capacitor-based and works to adjust the power factor as close to 1.0 (unity) as possible. Here's a rough idea of how it works:

Detection Of Power Factor

Power factor correction equipment monitors the power factor of the electrical system. It measures the phase difference between the voltage and current waveforms. A high power factor optimises the electrical system and makes better use of the components.

Calculation And Analysis

When the equipment detects a poor power factor, it calculates the level of reactive** power in the system. This power doesn't perform useful work but circulates between the source and the load, causing inefficiency.

**If you're unsure about what this is, we've added a short explanation further along.

Introduction Of Capacitors

If the power factor is lagging (below 1.0) due to an excess of reactive power, PFC equipment introduces capacitors into the system. Capacitors generate reactive power, effectively offsetting the excess power in the system. This process leads to a more balanced and efficient power factor.

Balancing The Power Factor

As the capacitors release reactive power, the power factor of the system improves and gets closer to unity. This balancing of the power factor optimises the use of electrical power, reducing losses and enhancing efficiency.

The Difference Between Reactive, Apparent And Active Power

Active Power (Real Power):

  • Active power (measured in watts, W) is the actual power that performs useful work in an electrical circuit. It is the power that powers devices and appliances.
  • It represents the portion of the power that is converted into mechanical work, heat, or other useful forms of energy.
  • Active power is the power that you are billed for by your utility company because it is the power that is genuinely consumed in the circuit.

Reactive Power:

  • Reactive power (measured in volt-amperes reactive, VAR) is a component of apparent power that doesn't perform useful work but instead circulates between the source and the load.
  • It arises due to the phase difference between the voltage and current in an alternating current (AC) circuit. In AC circuits, current and voltage are not always perfectly in phase.
  • Reactive power is needed to establish and maintain the electromagnetic field in inductive loads (e.g., motors, transformers) and is returned to the source in capacitive loads.

Apparent Power:

  • Apparent power (measured in volt-amperes, VA) is the combination of both active (real) power and reactive power.
  • It represents the total power that flows through an electrical circuit and is analogous to the magnitude of the total power in the circuit.
  • Apparent power can be thought of as the "hypotenuse" in a right-angled triangle, with active power as one side and reactive power as the other side.

In summary, active power (real power) is the useful power that performs work, while reactive power is the non-working power necessary to establish and maintain electromagnetic fields. Apparent power is the vector sum of active and reactive power and represents the total power flow in the circuit. The relationship between these concepts is described by the power factor, which is the ratio of active power to apparent power, and it quantifies the efficiency of electrical systems.

Automatic Control

PFC equipment often operates automatically, continuously monitoring the power factor and adjusting the capacitors as needed to maintain a near-unity power factor.

By improving the power factor of an electrical network, PFC ensures that the electricity is used more efficiently, reducing energy consumption and operational costs for businesses.

Why Is PFC Necessary?

  • Enhanced Energy Efficiency. PFC enhances the efficiency of electrical systems by aligning voltage and current waveforms. When the factor is closer to unity (1.0), electricity is utilised more efficiently, reducing energy wastage.
  • Cost Savings. Improved PFC results in reduced energy consumption, which can translate into lower electricity bills. Many UK utility companies charge commercial and industrial customers based on their power factor, making PFC a cost-effective choice.
  • Optimal Equipment Performance. Electrical equipment and machinery operate more effectively when the power factor is balanced. PFC ensures that equipment functions optimally, reducing wear and tear and extending its lifespan.
  • Environmental Benefits. PFC contributes to environmental sustainability by reducing energy wastage and lowering carbon emissions. It helps businesses align with their environmental goals.
  • Penalty Avoidance. Some UK utility companies will impose reactive power charges on customers with poor power factors. Implementing PFC allows businesses to avoid these penalties and associated costs.
  • Voltage Stability. PFC helps stabilise the voltage supply, reducing voltage fluctuations that can be harmful to sensitive equipment.
  • Increased System Capacity. PFC can free up capacity within the electrical system, allowing businesses to add more equipment without the need for costly infrastructure upgrades.

In summary, PFC is vital for enhancing energy efficiency, reducing electricity costs, ensuring optimal equipment performance, addressing power quality issues and contributing to environmental sustainability, making it an integral aspect of managing electrical systems for businesses and industries in Headstone South.

The Installation Process

The Installation Process


The Headstone South Powervolt Team team always strives to minimise any disruption to your work schedule and will be happy to discuss the best time to visit. The installation process - and the timescale involved - will vary according to the size and complexity of the project.

However, the process typically follows these steps:

Initial Assessment. The process begins with a thorough assessment of your electrical system. During this phase, our experts evaluate the existing power factor and identify areas where PFC equipment is needed. All the equipment will be thoroughly tested to ensure it is working perfectly.

Design and Equipment Selection. Following the assessment, the design phase commences. Careful selection of the appropriate PFC equipment tailored to your system's needs and expected load variations is carried out.

Equipment Procurement. Once the design is finalised, the equipment procurement phase begins. Our aim is to ensure that all required components are readily available for installation.

Installation. The physical installation of PFC equipment is a relatively quick process. During this phase, capacitors and other components are connected to your electrical system at strategic points to enhance the power factor.

Testing and Calibration. After installation, the PFC system undergoes testing and calibration to verify that it is functioning optimally and has corrected the power factor as intended.

Fine-Tuning. In some instances, additional fine-tuning may be necessary to ensure the PFC system is fully optimised.

Please note that the duration of each stage may vary depending on the specific requirements of your business and the complexity of your system. We aim to implement PFC equipment efficiently and effectively to maximise energy efficiency and cost savings for your organisation.

Power Factor Correction Maintenance Headstone South


No electrical equipment lasts forever - unfortunately! However, there are ways to extend the life of your PFC.

First, it has to be installed correctly by qualified professionals, like the Powervolt Team team.

Next, you must look after the PFC and check for issues such as capacitor deterioration. This problem can increase the chances of harmonic magnification/absorption, which could cause multiple capacitors to fail.

Also, the dielectric inside breaks down with excessive use, especially when the device is exposed to more external events than is good for it.

Aside from these, your reactive power charge savings will gradually decrease over time without regular maintenance, and there's a chance that the system will become detuned, leading to stress on other electrical equipment. It's also important to make sure that the control relay is not giving false reports.

To avoid all of these issues, we recommend annual servicing and inspection and ensure that your PFC continues to function at its optimal levels.

What's The Lifespan Of Power Factor Correction Equipment?

Most will last between 10 and 20 years, but as there are many different types and sizes facing a range of uses and electrical loads, it's impossible to put an exact figure on this.

However, with regular inspection and maintenance, we ensure that your PFC continues to run smoothly for years to come.
