what is power factor and why is it important

You may not have heard of Power Factor or these fixes, but running your electrical equipment at the best power factor ratio can help lower your business costs and help protect the environment. .

What is power factor?

Contents

Power factor is a measure of how efficiently you use your electricity. Many different types of energy are used to give us electrical energy. This power is split between something called Working Power and Reactive Power. Working energy is used in all electrical devices to create things like heat, light, and motion. This power is measured in kW or kilowatts. Reactive power is used by an inductive load, such as a motor, to generate and maintain an active magnetic field. Your device’s active and reactive power make up your Apparent Power. Hope all of you are still with me! Power Factor is the ratio between Working Power and Apparent Power Read: What is Power Factor and why is it important All motors in the form of machines, such as conveyors, Mixers, compressors, elevators and escalators all have known performance ratings as a power factor. It is a measure of “efficiency” and has values ​​from 0 to 1, where 1 is 100% efficiency. The power factor is not good – less than 0.95, resulting in more current flowing than necessary. A good power factor is greater than 0.95, so power is used more efficiently. The “perfect” Power Factor is 1.

For a typical unregulated industrial supply, the power factor is about 0.80. This means it is 80% efficient and will consume 20% more power. So you need more generators and a heavier distribution network, resulting in higher energy bills.

What is power factor correction?

The easiest way to improve Power Factor is to use Power Factor correction capacitors in parallel with the motor or lighting circuit connected. These can be applied at the equipment, distribution panel or at the origin of the installation. They improve the overall electrical efficiency of your power supply, so less current is required to achieve the same results. An example of this could be a 1MVA transformer with a Power Factor of 0.75. This can only provide 750KW load. Increasing this to a power factor of 0.95 can provide an additional 200KW of load. It can also reduce current and power loss in cables and transformers. Overall, it can reduce the number of KWH units consumed. Using this example, a 200KVA savings chargeable load saves £300 per month on a typical charge of £1.50 per KVA of the maximum demand charge for the supply. Power factor correction can also reduce Power Factor charges and climate tax fees.

What are the advantages of power factor correction?

There are several advantages to installing power factor correction devices into your power supply. These include: • Reduce electricity bills • Increase load carrying capacity in your existing circuits • Reduce I2R losses in transformers and distribution equipment • reduce overall power system losses • Increase lifespan equipment • Reduces electrical burden on cables and electrical components.
