Power Factor

Power Factor –

The Hidden Cause of High Energy Bills?

Poor power factor at your office/plant might add to superfluously high energy costs. Your electricity bill ought to demonstrate that your meter measures either kW or kVA. These are not the same! In the event that you are charged in view of kW, then poor power variable is most likely not a financial sympathy toward your business, unless your energy conveyance organization charges a (poor) control figure punishment. Regularly, punishments are evaluated if power factor consider measured at the meter is decreasing or we can say poor power factor. On the other hand, in the event that you are charged based on measured kVA, then poor power figure interprets straightforwardly high energy costs.

How Does This Work?

Many electrical devices, for example, motors and even some lighting items can add to general poor power factor. For instance, a Self ballats HPML consumes 70W (genuine power) and works at 230V. Notwithstanding, this specific light is marked 0.26A. 230V X 1.20A = 276 VA, (evident power), which is far higher than the 70W. This means this item has an extremely poor 48% power figure. The electric service organization must convey the evident power noted above with a specific end goal to address the light’s issues. In the event that the electric meter is recording energy use as kW, then the service organization is getting bamboozled by the contrast between the clear power provided, and the genuine power appeared on the meter. In certain energy showcases, this deficiency is designated to all energy clients, however in different markets, the deficit is assigned specifically to the individual offices that have poor power calculate the type of a weighty penalty.


To be reasonable for fluorescent lighting innovations, quality fluorescent stabilizer for general lighting in workplaces and modern industrial settings can have a close perfect power power factor, and these “good” sorts of lighting systems are significantly more typical in business and mechanical settings than the purchaser review item refered to above. Other than purchaser review smaller fluorescent lighting, other lighting systems that may add to poor power figure incorporate attractive, (or center and curl), fluorescent, metal halide, high weight sodium and other high force release counterbalances.


In a mechanical setting, electric motors add to poor general power factor more than some other office system. power factor for motors with similar specifications can change generally, and power factor for two indistinguishable motor will differ broadly relying upon how far they are physically situated from the electrical board and how they are stacked.

Correcting Poor Power Factor

Including capacitance (modern size capacitors) to counter reactance (reactive power) can correct poor power factor on a facility-wide basis. In the above case of the light, the reactive power is 23.2 VAR. Adding a 18.3 VA capacitor to the circuit will bring the power factor to more noteworthy than 95%. At the point when these counts are connected on an office wide premise to decide an effectively measured capacitor system, the final product will be drastically lessened energy costs when a power factor punishment exists or when an electric meter records kVA rather than kW. Contact your Good Energy agent today to mastermind a building study to decide how much capacitance ought to be added to your office’s electrical system to correct poor power factor.
