Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 520.79 ÷ 575 = 520,791 ÷ 575 = 905.72 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

520,791 ÷ (0.85 × 575) = 520,791 ÷ 488.75 = 1,065.56 A

AC Three Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (√3 × PF × V_L-L), where V_L-L is the line-to-line voltage

520,791 ÷ (1.732 × 0.85 × 575) = 520,791 ÷ 846.52 = 615.2 A

Fluorescent lamps	0.95	550.44 A
LED lighting	0.9	581.02 A
Synchronous motors	0.9	581.02 A
Typical mixed loads	0.85	615.2 A
Induction motors (full load)	0.8	653.65 A
Computers (without PFC)	0.65	804.49 A
Induction motors (no load)	0.35	1,494.06 A

AC Conversion Comparison

On DC, 520.79kW at 575V draws 905.72A. AC single-phase at PF 0.85 pulls 1,065.56A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 615.2A per line since the same 520.79kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	520,791 ÷ 575	905.72 A
AC Single Phase (PF 0.85)	520,791 ÷ (0.85 × 575)	1,065.56 A
AC Three Phase (PF 0.85)	520,791 ÷ (1.732 × 0.85 × 575)	615.2 A
