3-Phase Power Calculator

Calculate active power (kW), apparent power (kVA), and reactive power (kVAR) from line parameters in a three-phase system.

Purpose of this Tool: Analyze 3-phase circuits and load balances for sizing components like electric panels and busbars.

• Apparent Power (kVA):S_{kVA} = \frac{\sqrt{3} \times V_{LL} \times I_{Line}}{1000}

• Active Power (kW):P_{kW} = S_{kVA} \times PF

• Reactive Power (kVAR):Q_{kVAR} = S_{kVA} \times \sin(\arccos(PF))
