Easily calculate three-phase electric power (kW, kVA), current in Amps, or voltage with our free online tool. Essential for electrical engineers, electricians, and anyone working with 3-phase systems to ensure efficient and safe electrical design.
Formula:
Real Power (kW)
kW = (√3 * VLL * I * PF) / 1000
Apparent Power (kVA)
kVA = (√3 * VLL * I) / 1000
Where:
- VLL = Line-to-Line Voltage (Volts)
- I = Line Current (Amperes)
- PF = Power Factor (dimensionless, typically between 0 and 1)
- √3 ≈ 1.732 (Square root of 3)
