# Kilovolt-amp (kVA)

Watt and volt-ampere are the units used for the measurement of two basic types of electric power, real electric power and apparent electric power. Real electric power is calculated in watts whereas the apparent power is the combo of real electric power plus a reactive power and is described in volt-amperes. The kilovolt ampere is a larger entity of the volt-ampere.

kVA is kilo-volt-ampere. kVA is a unit of apparent power, which is electrical power unit.

1 kilo-volt-ampere is equal to 1000 volt-ampere:

1kVA = 1000VA

1 kilo-volt-ampere is equal to 1000 times 1 volt times 1 ampere:

1kVA = 1000⋅1V⋅1A

## kVA to volt-amps calculation

The apparent power S in volt-amps (VA) is equal to 1000 times the apparent power S in kilovolt-amps (kVA):

S(VA) =  1000 × S(kVA)

## kVA to kW calculation

The real power P in kilowatts (kW) is equal to the apparent power S in kilovolt-amps (kVA), times the power factor PF:

P(kW) =  S(kVA) × PF

## kVA to watts calculation

The real power P in watts (W) is equal to 1000 times the apparent power S in kilovolt-amps (kVA), times the power factor PF:

P(W) =  1000 × S(kVA) × PF

## kVA to amps calculation

### Single phase kVA to amps calculation formula

The current I in amps is equal to 1000 times the apparent power S in kilovolt-amps, divided by the voltage V in volts:

I(A) = 1000 × S(kVA) / V(V)

### 3 phase kVA to amps calculation formula

#### Calculation with line to line voltage

The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovolt-amps, divided by the square root of 3 times the line to line RMS voltage VL-L in volts:

I(A) = 1000 × S(kVA) / (3 × VL-L(V) )

#### Calculation with line to neutral voltage

The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovolt-amps, divided by 3 times the line to neutral RMS voltage VL-N in volts:

I(A) = 1000 × S(kVA) / (3 × VL-N(V) )

How much power is a kilovolt?

In essence, 1 kVA is equivalent to 1,000 amps of volts. Volts are a measure for electrical tension, amps are a measure of current electrical. The term "apparent power" (the total value for power complex) is the sum of voltage and amps.15-Jun-2017
