Engineering planning checklist

Industrial Power Factor & Demand Optimization

Estimate reactive compensation, apparent-power reduction, and three-phase current before and after a planning-level power-factor correction check.

Use as a checklist, not an automated design workflow. Complete and verify each calculation independently. Only explicit carry-forward links move a compatible value; all other inputs remain your responsibility.

What this workflow covers

Estimate reactive compensation, apparent-power reduction, and three-phase current before and after a planning-level power-factor correction check.

This 3-step checklist is intended for electrical engineer. Confirm each linked calculator's units, formula, assumptions and operating limits before using the result in a project decision.

Sequence Execution
1

Three-Phase Electrical Power

Calculate real power (kW), apparent power (kVA), reactive power (kVAR), and full-load line current for 3-phase AC systems.

WORKFLOW INSTRUCTION:Establish measured real, apparent, and reactive power for the balanced three-phase load.
2

Power Factor Correction & Capacitor Sizing

Scope-limited calculation

Estimate reactive compensation, apparent-power reduction, and three-phase current before and after improving a plant power factor.

WORKFLOW INSTRUCTION:Compare measured and target power factor to estimate required kVAR compensation and the resulting apparent-power and current reduction.
3

Transformer kVA Rating & Load Sizing (IEC 60076)

Scope-limited calculation

Calculate minimum required transformer kVA capacity rating and secondary full-load current based on active load (kW) and power factor.

WORKFLOW INSTRUCTION:Recheck planning-level transformer kVA against the corrected operating power factor; complete harmonics, protection, and utility-demand studies separately.
