Power Factor Correction Equipment
Manufacture - Maintenance - Installation - Products - Services
Power Quality Improvement Services Ltd. are suppliers of power factor correction equipment and services to companies looking to reduce their carbon footprint and electricity costs.
Whether your business operates from a new building or you have an established premises, we can provide solutions to improve power quality and electrical efficiency. Our engineers have worked with all types of industry to deliver power factor correction projects, we are now uploading images and posts of our work in our Blog.
Inductive loads are applied to electrical systems by equipment used in all types of manufacturing, industrial and commercial processes. The inductive demand generates the reactive power measured on an electrical system.
The larger the reactive component of the power, without correction, the lower the power factor will be.
A low power factor will increase all the electrical values based around the current, increasing KW losses, heat in the system and electricity costs. A higher maximum demand is achieved and a higher 'agreed availability' with the supplier is required. In extreme cases the supplier may add 'reactive charges' to the electricity bill.
A system with a low power factor can also suffer faults and a reduced lifespan of motors and similar electrical equipment.
The solution to reduce reactive power in a low voltage electrical system is power factor correction equipment.
Power factor correction units are connected to a low voltage electrical system to react to the inductive loads by switching capacitor banks into circuit. The capacitance near eliminates the reactive power, reducing the current, maximum demand and KW usage of the supply.
The effect of a consistent power factor above 0.98 is reduced electricity costs, increased system capacity and an improved electrical environment for equipment.
Power factor correction equipment is usually installed or integrated with LV switchgear of a site. The annual maintenance of power factor correction equipment is necessary and recommended due to the natural deterioration of capacitor output. The deterioration of power factor correction units is not always obvious, particularly if without modern controllers which indicate equipment faults and low capacitor output.
Included in our annual maintenance service is a full report indicating capacitor output, component operation and equipment condition. With recommendations if applicable for improvement or repair.
