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

Specialist Power Factor Correction Services

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:

  • Design & Build: From initial concept to installation and decommissioning.
  • Custom Capacitors: In-house manufacturing of power factor correction capacitors up to 33kV for precise solutions.
  • Dynamic Compensation Systems: Advanced systems for managing reactive power in real-time.
  • Equipment Installation & Support: Professional installation, technical support, and maintenance.
  • Repairs: Maintenance and repairs for all PFC equipment, regardless of manufacturer.

What Are The Benefits?

Investing in power factor correction offers numerous advantages for businesses across industries, including:

  • Lower Energy Costs: By reducing reactive power, businesses can minimise energy waste and lower electricity bills.
  • Improved System Efficiency: Power factor correction optimises the use of electrical systems, reducing strain on equipment and extending its lifespan.
  • Reduced Carbon Footprint: Improved efficiency leads to less energy consumption, contributing to environmental sustainability.
  • Enhanced Equipment Performance: Minimised voltage drops and harmonics ensure smooth operation and reduced maintenance needs.
  • Avoidance of Utility Penalties: Many energy providers impose penalties for poor power factors. Correcting this ensures compliance and cost savings.

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.

Power Factor Correction Equipment

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.

Benefits of Using The Latest PFC Equipment

  • Extend Equipment Lifespan: Preserve and optimise the life of your electrical assets.
  • Increase Supply Capacity: Free up network capacity to avoid costly supply upgrades and support future expansion.
  • Protect Your Assets: Minimise the risk of damage and reduce operational downtime.
  • Maximise Energy Efficiency: Reduce energy bills, reactive power charges, and carbon emissions while ensuring the most efficient energy use.
  • Immediate Return on Investment: Enjoy fast, cost-effective installation with typical payback periods of 12–24 months.
  • Stabilise Power Supply: Ensure a reliable and stable electrical system while reducing transformer and distribution losses.

Q&A About Our Power Factor Correction Solutions

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.
