We are suppliers of power quality products and services to companies looking to reduce their carbon footprint and electricity costs. Whether your business operates from a new building with new equipment or you have an established business and premises we can provide electrical engineering solutions to improve the power quality and electrical efficiency of your site. Professionally and proactively our engineers have worked with all types of industry to deliver cost effective electrical efficiency, we are now uploading images and posts of our work in our blog. Case studies of our work have been used to produce articles for theenergyst.com and other publications which can be seen in the gallery below.

Inductive loads are applied to an electrical supply by electrical equipment on LV electricity supplies in all types of manufacturing, industrial and commercial processes. This load generates the reactive power of an electrical system. The larger the reactive component of the power used in a power supply, the lower the power factor will be. A low power factor increases all the electrical values based around current, increasing losses, heat in the system and electricity costs. In extreme cases a provider may add `reactive charges` to an electricity bill. The electrical engineering solution to reduce the reactive power is power factor correction equipment.

PFC equipment is used to counter inductive loads and is applied to an LV electrical supply to react to inductive loads with capacitance. The capacitance, applied correctly to the circuit almost completely eliminates the reactive power, reducing the current, maximum demand and KW usage of the supply.

The switching of heavy inductive loads on an electrical system left uncorrected can also create faults and reduce the lifespan of electrical equipment caused by additional heat and instability of the supply power quality.

PFC equipment is usually installed with LV switchgear. The deterioration of this equipment is not always obvious. The annual maintenance of this equipment is recommended due to the natural deterioration of capacitor output. As the capacitor output deteriorates or occurrence control faults make a good power factor difficult to achieve.

Our products and services will reduce electricity costs and improve electrical efficiencies. If you are unsure of the power quality of the electrical supplies of your site? Or are searching for UK power factor correction companies or require a power quality evaluation for your business.

Significant electricity consumption and maximum demand reductions can be achieved with a power factor above 0.98 on the electricity supply for your business.

For all PFC equipment that we recommend, a payback time of less than 2 years is targeted, in most cases this is much less.

PQIS supply capacitors, reactors and other products used in power factor correction equipment and harmonic filtration. We have selected components and processes to supply our customers with power quality products and services of the highest quality and reliability at a price which is cos effective.

To discover how your business can reduce energy costs and reduce carbon emissions through an improved electrical efficiency.
