Power Factor Correction

 Jenkinson's are experts in specifying and installing energy-saving Power Factor Correction Equipment, which can substantially reduce your electricity bills.

Benefits of Power Factor Correction:
• Power Consumption Reduced
• Electricity Bills Reduced
• Electrical energy efficiency improved
• Extra kVA availability from the existing supply
• Transformer and distribution equipment losses reduced
• Voltage drop reductions in long cables

What is Power Factor?
Power Factor is a measure of how efficiently electrical power is consumed.
The ideal Power Factor is unity - or one. Anything less than one, (or 100% efficiency), means that extra power is required to achieve the actual task at hand.

How is Power Factor caused?
Most electrical equipment such as motors, compressors, welding sets and even fluorescent lighting, create what is known as an inductive load on the supply. This extra energy is known as Reactive Power, which can also be interpreted as wasted power and an extra burden on the electricity supply – it costs you money for no useful purpose!

How can Power Factor be Corrected?
We can achieve this by the addition of capacitors to the electrical network, which compensate for the Reactive Power demand of the inductive load and thus reduce the burden on the supply.

Energy Efficiency - Energy Efficient Lighting and Heating

Utilising new developments in lighting and lighting control technology, together with available grants, we may be able to save you up to 60% in energy costs with proven returns on investment in as little as 1 year. We can perform a free survey highlighting potential energy savings in all applications of lighting.

We have all taken on board the switch from incandescent bulbs to compact fluorescent (CFLs), "energy-saving bulbs". But there have been other huge developments in lighting and heating technology in recent years, aimed at minimising energy usage and increasing efficiency in commercial and industrial installations.

LED lighting is now available as a replacement for most types of lighting and using a fraction of the power. Sophisticated control systems utilizing daylight dimming and occupancy sensing can radically reduce energy consumption.
