How to convert kW to Volts

DC kW to volts calculation formula

V(V) = 1000 × P(kW) / I(A)

The voltage V in volts (V) is equal to 1000, multiplied by the power P in kilowatts (kW), divided by the current I in amps (A).

So,

V = 1000 x kW / A
volt = 1000 x kilowatt / amp

For example:

Power (P) = 5kW
Phase current (I) = 2,5A

Voltage (V) = 1000 x 5kW / 2,5A = 2000V

AC single phase kW to volts calculation formula

V(V) = 1000 × P(kW) / (PF × I(A))

The voltage V in volts (V) is equal to 1000, multiplied by the power P in kilowatts (kW), divided by the power factor PF, multiplied by the current I in amps (A).

So,

V = 1000 x kW / (PF x A)
volt = 1000 x kilowatt / (PF x amp)

For example:

Power (P) = 5kW
Phase current (I) = 2,5A
PF = 0,5

Voltage (V) = 1000 x 5kW / (0,5 x 2,5A) = 4000V

AC three phase kW to volts calculation formula

VL-L(V) = 1000 × P(kW) / (√3 × PF × I(A))

The line to line RMS voltage VL-L in volts (V) is equal to 1000, multiplied by the power P in kilowatts (kW), divided by square root of 3, multiplied by the power factor PF, multiplied by the current I in amps (A).

So,

V = 1000 x kW / (√3 × PF x A)
volt = 1000 x kilowatt / (√3 × PF x amp)

For example:

Power (P) = 5kW
Phase current (I) = 2,5A
PF = 0,5

Voltage (V) = 1000 x 5kW / (√3 × 0,5 x 2,5A) = 2309,401V
