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 approach ensures the installation of the most effective power factor correction equipment, optimising mains voltages for maximum efficiency. Our solutions eliminate harmonic generation issues and deliver superior system performance.
Our power factor engineers can provide you with the following:

Investing in power factor correction offers numerous advantages for businesses across industries, including:
At Johnson & Phillips, we deliver these benefits through our expertly designed power factor correction devices and systems. From in-house manufactured capacitors to advanced dynamic compensation solutions, our equipment is built to ensure maximum efficiency and reliability.
Addressing a low power factor with advanced equipment, such as PFC capacitors, can significantly improve energy efficiency and system reliability. Installing capacitors at the main power supply is a straightforward solution for many systems, but more complex setups may require custom-designed equipment tailored to specific machinery. That’s where our expertise comes in, delivering specialised solutions for unique power factor challenges.
It’s important to remember that power factor correction equipment has a finite lifespan. Equipment installed decades ago may no longer perform optimally due to wear, changes in site layout, or evolving power demands. Therefore, a professional resurvey of your site can identify poor power factor issues and determine if an equipment upgrade or overhaul is necessary.
At Johnson & Phillips, we provide power factor correction units designed for long-term performance and efficiency. Once installed, these units deliver lasting savings by significantly reducing reactive power charges, often paying for themselves within a short period. All of our capacitors are manufactured in-house, ensuring the highest standards of quality and reliability.
In addition to supplying and installing PFC equipment, we offer comprehensive maintenance, repair, and technical support services, including 24-hour disaster recovery solutions. Whether you’re looking to optimise an existing system or require a new installation, our team is here to help.
As a UK-based manufacturer with a nationwide and international client base, we specialise in delivering tailored solutions to meet the unique energy needs of your business. Contact one of our experts today to explore how we can support your power factor correction requirements.
Our power factor correction case studies showcase real-world examples of how Johnson & Phillips has helped businesses optimise their energy efficiency, reduce costs, and improve the reliability of their electrical systems. From manufacturing facilities to renewable energy projects, these case studies highlight the tailored solutions we’ve delivered to address unique power challenges.
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:
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.
