One of the top issues that customers choose when choosing a generator is the right size for their needs. Generator size is measured in Kilovolt-Amperes (KVA). KVA is not a widely known term outside of the generator industry. It can be confusing to determine the size you require.

Watching: What is Kva

However, you can tell how much power you need if you convert from KVA to KW (kilowatt). So, let’s learn how to distinguish between KVA and KW? How do you convert between these two units?

What is the correct formula to convert KVA to KW?

## How to distinguish between KVA and KW

?Watt (abbreviated as W) is the unit of power measurement P in the international system of measurement. Watt is named after James Watt.

Power indicates the change in energy ΔE over a period of time Δt. 1 Watt is the change of energy 1 Joule in 1 second.

The electrical power at time t is calculated by P(t) = U(t) · I(t). U(t). Where, I(t) are the r.m.s. values ​​of the voltage and current at t, when they are not out of phase.

KVA, on the other hand is a measure of the strength of an electric current. If KW is how much energy you can work with then KVA tells you the total amount being used in the entire system.

If the efficiency of an electrical system were perfect, then KW would be equal to KVA. But since no system is completely efficient, not all of the apparent power will be converted to useful output.

## Convert KW to KVA

To convert KW to KVA, you first need to know the efficiency (or power factor) of the system. Power Factor (PF) is measured on a scale of 0 to 1.

On average, a generator will have a power factor of 0.8.

The formula to convert KW to KVA is: KW / PF = KVA, for example: 200 KW / 0.8 pf = 250 KVA

The formula to convert KVA to KW is: KVA x PF = KW, for example: 250 KVA x 0.8 pf = 200 KW

Although there may be a specification for the generator size you need, you are not sure if that is the correct number? Minh Thanh Power will help you. With a team of engineers, our technicians assist in distinguishing between KVA and KW efficiently. At the same time, determine the most suitable equipment for each business or company.
