Power conversion calculators project basis

Convert Australian 230/400 V a.c. power, current, kW, kVA, kVAr, energy use and tariff inputs into review-ready electrical worksheets. These calculators support Australian design, estimating, installation and verification preparation. Keep the circuit, equipment, route, supply arrangement and source data with the result before it is used in a project record.

Confirm the nominal 230/400 V a.c. or project-specific voltage basis, 50 Hz context where applicable, phase arrangement, metric units, manufacturer information, DNSP or authority conditions and current project documents before applying a result.

Check entered values, supply arrangement, cable or equipment data, product limits, DNSP or authority conditions and review limits before using the result.

Records covered

  • Load currentConvert load power or apparent power to current. Inputs: W, kW, VA or kVA, phase arrangement, voltage and power factor. Output: Current estimate for calculation support and downstream checks.
  • kVA, kW and power factorConvert between apparent power, real power and power factor. Inputs: Known power value and power factor or target conversion mode. Output: Electrical relationship result with formula basis shown.
  • Power factor correctionEstimate correction kVAr from existing PF and target PF. Inputs: kW or existing kVA, existing power factor and target power factor. Output: Correction estimate requiring equipment, utility and manufacturer review.
  • Energy costEstimate kWh and running energy cost from entered load, usage and tariff values. Inputs: Load reference, kW, operating hours, days, duty factor and c/kWh tariff. Output: Energy-cost estimate using user-entered tariff values without retailer plan comparison.
  • Tariff scenarioCompare two manually entered energy and daily supply charge scenarios. Inputs: Daily kWh, period days, scenario A rate and supply charge, scenario B rate and supply charge. Output: Scenario-cost difference with tariff boundary notes, not retailer plan advice.
  • Load profile kWhSummarise kWh across entered load-profile rows. Inputs: Load block labels, kW, hours, duty factors and period days. Output: Daily and period kWh profile summary with peak row and largest energy row.

Review before applying

Power conversion calculator results are preparation records. Keep entered values beside current Australian requirements, DNSP or authority conditions, manufacturer information and project documents before applying a result.

Recheck the selected calculator whenever the supply arrangement, equipment data, route length, tariff basis, measurement method or project document set changes.
