Formulas for Three Phase Current (Amps):
- For Real Power (kW):
- Line-to-Line (VLL):
I = (PkW × 1000) / (√3 × VLL × PF) - Line-to-Neutral (VLN):
I = (PkW × 1000) / (3 × VLN × PF)
- Line-to-Line (VLL):
- For Apparent Power (kVA):
- Line-to-Line (VLL):
I = (SkVA × 1000) / (√3 × VLL) - Line-to-Neutral (VLN):
I = (SkVA × 1000) / (3 × VLN)
- Line-to-Line (VLL):
Where:
- I = Current in Amperes (A)
- PkW = Real Power in Kilowatts (kW)
- SkVA = Apparent Power in KiloVolt-Amperes (kVA)
- VLL = Line-to-Line Voltage in Volts (V)
- VLN = Line-to-Neutral Voltage in Volts (V)
- PF = Power Factor (dimensionless, 0 to 1, e.g., 0.8)
- √3 ≈ 1.732 (Square root of 3)
