Kilovolt (KV) to Watt (W) Conversion

To convert kilovolts (kV) to watts (W), you need more informationโ€”voltage alone is not enough. You must also know:

The current (I) in amperes (A)

The type of current: DC, AC Single Phase, or AC Three Phase

The power factor (PF) for AC circuits (usually between 0.7โ€“1)

DC Systems

Formula: P = V ร— I

Power (W) = Voltage (V) ร— Current (A)

For kV to W: P = (kV ร— 1000) ร— I

AC Single Phase

Formula: P = V ร— I ร— PF

Power (W) = Voltage (V) ร— Current (A) ร— Power Factor

For kV to W: P = (kV ร— 1000) ร— I ร— PF

AC Three Phase Line-to-Line (L-L)

Formula: P = โˆš3 ร— VL-L ร— I ร— PF

Power (W) = โˆš3 ร— Line-to-Line Voltage (V) ร— Line Current (A) ร— Power Factor

For kV to W: P = โˆš3 ร— (kV ร— 1000) ร— I ร— PF

AC Three Phase Line-to-Neutral (L-N)

Formula: P = 3 ร— VL-N ร— I ร— PF

Power (W) = 3 ร— Line-to-Neutral Voltage (V) ร— Line Current (A) ร— Power Factor

For kV to W: P = 3 ร— (kV ร— 1000) ร— I ร— PF

Where:

  • P = Power in watts (W)
  • V = Voltage in volts (V)
  • kV = Kilovolts (1 kV = 1000 V)
  • I = Current in amperes (A)
  • PF = Power Factor (ranges from 0 to 1, typically 0.8 to 0.95 for most applications).
