Rack PDU Phase Balance Calculator

Quantify phase-current imbalance for a three-phase rack PDU from measured per-phase real power.

Inputs

System inputs

Range: 0–10,000 kW

Enter measured or modeled real power on phase A in kW for the same interval.

Range: 0–10,000 kW

Enter measured or modeled real power on phase B in kW for the same interval.

Range: 0–10,000 kW

Enter measured or modeled real power on phase C in kW for the same interval.

Range: 1–1,000 V

Enter RMS line-to-neutral voltage in V at the rack PDU; use a consistent voltage for all phases.

Range: 0.1–1 decimal

Enter phase power factor as a decimal; the simplified model applies one value to all phases.
