Kilovolt (KV) to Watt (W) Conversion
To convert kilovolts (kV) to watts (W), you need more informationโvoltage 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 0.7โ1)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 = โ3 ร VL-L ร I ร PF
Power (W) = โ3 ร Line-to-Line Voltage (V) ร Line Current (A) ร Power Factor
For kV to W: P = โ3 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).
