## Single phase amps to kVA calculation formula

So The apparent power [S] in kilovolt-amps is equal to current I in amps, times the voltage [V] in volts, divided by .

S(kVA) = I(A) × V(V) / 1000

#### Example 1

What is the apparent power in kVA when the phase current is 14A and the RMS voltage supply is 120V?

Solution:

S = 14A × 120V / 1000 = 1.68kVA

#### Example 2

What is the apparent power in kVA when the phase current is 15A and the RMS voltage supply is 140V?

Solution:

S = 15A × 140V / 1000 = 2.1kVA

#### Example 3

What is the apparent power in kVA when the phase current is 25A and the RMS voltage supply is 150V?

Solution:

S = 25A × 150V / 1000 = 3.75VA

## 3 phase amps to kVA calculation formula

#### Calculation with line to line voltage

So The apparent power [S] in kilovolt-amps is equal to phase current [I] in amps, times the line to line RMS voltage [VL-L] in volts, divided by .

S(kVA) = 3 × I(A) × VL-L(V) / 1000

#### Example 1

What is the apparent power in kVA when the phase current is 14A and the line to line RMS voltage supply is 150V?

Solution:

S = 3 × 14A × 150V / 1000 = 3.637kVA

#### Example 2

What is the apparent power in kVA when the phase current is 15A and the line to line RMS voltage supply is 180V?

Solution:

S = 3 × 15A × 180V / 1000 = 4.677kVA

#### Example 3

What is the apparent power in kVA when the phase current is 20A and the line to line RMS voltage supply is 290V?

Solution:

S = 3 × 20A × 290V / 1000 = 10.046kVA

#### Calculation with line to neutral voltage

The apparent power [S] in kilovolt-amps is equal to phase current [I] in amps, times the line to neutral RMS voltage VL-N in volts, divided by .

S(kVA) = 3 × I(A) × VL-N(V) / 1000

#### Example 1

What is the apparent power in kVA when the phase current is 12A and the line to neutral RMS voltage supply is 140V?

Solution:

S = 3 × 12A × 140V / 1000 = 5.04kVA

#### Example 2

What is the apparent power in kVA when the phase current is 12A and the line to neutral RMS voltage supply is 150V?

Solution:

S = 3 × 12A × 150V / 1000 = 5.4kVA

#### Example 3

What is the apparent power in kVA when the phase current is 12A and the line to neutral RMS voltage supply is 190V?

Solution:

S = 3 × 12A × 190V / 1000 = 6.84kVA
