How kw to kva?

In the kW to kVA calculations, the kW to kVA conversion formula is -

kW = kVA × PF

Where,

kW is the unit estimating real power.

kVA is the unit estimating apparent power.

PF is the Power Factor.

In the kW to kVA conversion, kW is directly relative to kVA, which implies that-

When kW increments, kVA will increment.

When kW declines, kVA will diminish.

When kVA declines, kW will diminish.

When kVA increments, kW will increment.

In mathematical terms, we can write it as:

kW = kVA x PF

The conversion of kVA to kW; these two units of power are significant to solve many problems in Physics. kVA to kW formula is:

kVA= kW/PF

For example: If the Power factor is 0.2 and kW is 150 then kVA = 150/0.2 = 750 kVA.

To convert kW to kVA; The power units are essential to solve kVA calculations in Physics.

To convert kW to kVA-

kW=kVA×PF

Example: If the Power Factor is 0.2, and kVA is 150 then to convert kW to kVA

kW=150kVA×0.2 = 30kW

Just like kW to kVA conversion, A kilowatt-hour (kWh) is the measure of the energy a circuit working at a kilowatt of power moves through the span of 60 minutes. This unit is equivalent to 3,600,000 joules. The kilovolt-ampere (kVA) is the power rating of a circuit conveying 1,000 volts and an ampere or 1,000 amperes and a volt. A single kilovolt-ampere is comparable to a kilowatt. To change over from kilowatt-hours to kilovolt-amperes, you have to know just the time the circuit takes to move the energy. Measure the time length for which the circuit runs.

The main difference between kW (kilowatt) and kVA (kilovolt-ampere) is the power factor. kW denotes the unit of real power and kVA denotes the unit of apparent power. The power factor, which is defined and known, is, therefore, an approximate value (typically 0.8), and in the kW to kVA calculations, kVA value will always be more than the kW value.

Under industrial as well as commercial generators, kW is most commonly used in the US generators. The majority of the rest of the world mainly uses kVA as the set of generators.

To explain it a bit more, the kW rating is primarily the result of power output a generator can supply based on the engine’s horsepower. kW is figured by the horsepower rating of the times of engine 0.746. For example, if you have a 600 horsepower engine, it has a kW rating of 473. The kilovolt-amperes (kVA) are the generator capacity end. Generator sets are displayed with both ratings usually.

To determine the kW to kVA calculations ratio, the kW to kVA formula below is used.

0.8 (pf) x 750 (kVA) = 600 kW

1. Convert the Real Power in Watts to Apparent Power in kVA (Kilovolt amps).

Solution: S in kilovolt-amps (kVA) which is the apparent power is equal to the P in watts (W) which is the real power, divided by 1000 times the PF:

S(kVA) = P(W) / (1000 × PF)W

Watts divided by 1000 times the power factor is equal to kilovolt-amps.

kVA = kW / (1000 × PF

The Relation between KVA and KW is one the most interesting topics from the Class 11 and 12 Physics part which deals with Electrical concepts and their applications. At a higher level, the relationship between KVA and KW is one of the most talked-about in electrical engineering and electronics engineering. Hence, the relation between KVA and KW finds its relevance in school-level exams as well as higher technical examinations as well.

Hence, students should be ready with all the basic concepts at their fingertips which will ensure that they will be able to answer any questions appearing from the topic of the relation between KVA and KW. Vedantu has come to the rescue and solved all the queries of the students by providing free and necessary learning materials which will ensure that students will be able to grasp important concepts and tips and tricks to make sure they will be able to remember them as well. Here are the points to remember in the relation between KVA and KW:

Kilowatts and kilovolt-amps are both a measure of power, but they’re a little different. Kilowatts (kW) measure the real power in an electrical circuit, while kilovolt-amps (kVA) measure the apparent power.

In electrical equipment with an inductive characteristic, such as a generator or transformer, the real power and apparent power are often not equal.

Real power is the amount of power that does real work in the circuit and is always the same or less than the apparent power. Apparent power is determined by the magnitude of voltage and current that must be transmitted to the device.

For reactive (inductive and/or capacitive) loads, electrical energy is stored in the device and pushed back to the power supply as opposed to doing real work. This phenomenon is called reactive power and is measured in kilovolt-amps-reactive (kVAR). Therefore, typically we try to maximize the real power and minimize reactive power.

The ratio of real power to apparent power is called the power factor (PF) and is between 0 and 1, where 1 is a pure resistive load and both inductive and capacitive loads have a PF less than 1.

To convert from kilowatts to kilovolt-amps considering all of this, you’ll need a simple formula.

The formula to convert kW to kVA accounting for the power factor is:

S(kVA) = P(kW) ÷ PF

The apparent power S in kVA is equal to the real power P in kW divided by the power factor PF.

To convert to kVA, substitute the power in kW and the equipment power factor in the formula above.

• In the kW to kVA calculations, the kW to kVA conversion formula is -
• kW = kVA × PF.
• Where,
• kW is the unit estimating real power.
• kVA is the unit estimating apparent power.
• PF is the Power Factor.
• In the kW to kVA conversion, kW is directly relative to kVA, which implies that-

The conversion of kW to kva is very simple. To convert you need to divide the kw value with its power factor value.

kW to kVA conversion formula:

kW = kilowatts.

kVA = kilovolt ampere.

PF = Power factor.

Example:

If an AC has 22kW power and its power factor of 0.80 then find the kVA? We have kW = 22kW; PF = 0.80; kVA = ?

kW to kVA conversion formula:

kVA = kw / PF

The relation between kVA and kW is mathematically given as-

Where,

kW is directly proportional to kVA, which means that-

Power of AC and Power of DC varies as the relation between kVA and kW varies from alternating current circuits to direct current circuits. It can be mathematically written as follows-

Both the units of power, kVA and kW, are important in physics to solve many problems. The kVA to kW conversion formula is given by-

The formula to convert kW to kVA is given by

Hope you understood the relation between kW and kVA of electric current for alternating current(AC)circuits and Direct Current(DC) circuit.
