kva and kw

The amount of ‘real power’ in an electrical system is measured in kW. This indicates how much energy is turned into productive, usable output.

KVA, on the other hand, is a unit of power that measures ‘apparent’ power. If kW is the maximum amount of electricity you can work with, kVA is the total amount of power consumed in the system.

If an electrical system’s efficiency is excellent, then kW is equal to kVA. However, because no system is perfect, not all of the perceived power will be translated to meaningful output.

Kva and kW

The international system of units uses the units kVA and kW to measure power. The kVA, or KiloVolt-Ampere, is a unit of apparent power measurement. The total quantity of electricity in the system is referred to as this. kW, on the other hand, is a unit of measurement for the amount of energy transformed into a usable output. As a result, it is the power with which one can work. These two units have a proportional relationship. To convert between kVA and kW, we must first determine the system’s electrical efficiency. The Power Factor, which runs from 0 to 1, is another term for electrical efficiency. The closer the power factor number is to one, the more efficiently kVA is converted to kW.

Kilovolt-Ampere (kVA)

KiloVolt-Ampere is a measurement of a machine’s apparent power. A kVA stands for1000 VA. An electrical pressure is represented by a Volt, while an electrical current is represented by an amp. As a result, perceived power equals the product of a volt and an ampere. Although kVA refers to visible power, it is vital to realise that it is used to guarantee that the system has the required wiring capacity to transport the excess current even when the machine is not in use. The kVA rating of a generator is commonly displayed so that it may be determined if it can handle the increased current required by reactive loads.

 Kilowatt(kW)

The term “kilowatt” refers to the amount of actual power that is turned into a useful output. As a result, kW is also known as working power or actual power. Voltage and current are multiplied to get kW.

KW to kVA Conversion

The formula for kW to Kva conversion is:

 kW=kVA ×PF

Here kW is the real power 

kVA is the total amount of apparent power 

PF is the power factor

By rearranging the above formula we get,

 kVA=kW/PF

Difference Between kVA and Kw

The power factor is the difference between kW and kVA. The real or useable power is denoted by kW, while the perceived power is denoted by kVA. In kW to kVA conversions, the power factor, which is defined and known, has an approximate value of 0.8.The value of kVA is always bigger than the value of kW.

In the US system, kW is most typically used in industrial and commercial generators. The vast majority of the rest of the globe employs kVA. The kW rating is mostly determined by the generator’s power output as a function of the engine’s horsepower. The horsepower rating of an engine0.746 is frequently used to calculate kW. For example, if we had a 700 horse powerengine,

It will be rated at 522.2kW The generating capacity is measured in kVA. Both ratings are frequently displayed by the generators.

 kva kw conversion factor

Voltage and current combine to form real power, which is measured in volts (V)and amps (A).

The product of voltage and RMS current is apparent power; it’s almost volts (V) amps (A), but not quite. Because the voltage and current in AC circuits are not in phase, the real power is reduced to apparent power. We’re dealing with RMS current here, and the power factor comes in handy.

The power factor in a circuit is the proportion of real power kWto apparent power (Kva). Any number between -1 and 1 can be used. A power factor is a number between  lying between 0 and 1.

kVA To kW Formula

As you know , the power factor can be used to account for voltage and current not being in phase in AC circuits. We can derive the following kVA to kW formula from the equation above:

 PF=apparant power kVA+Real power (kW)

We now know how to convert kVA to kW using the above formula.
