kVA
kVA meaning as apparent power in Australian load, transformer and generator records.
kVA in Australian records
kVA means kilovolt-ampere. It is an apparent power unit used in Australian load, transformer, generator and supply-capacity records.
The unit matters because apparent power includes the voltage-current relationship before power factor is resolved into real power. When kVA appears beside 230/400 V a.c. calculations, the record should keep phase arrangement and power factor context visible. That makes the difference between a nameplate rating, a running load and a starting load easier to review later.
Where apparent-power values appear
kVA wording appears in generator load checks, transformer sizing notes, kVA/kW calculators and power-factor charts. It is common where equipment ratings are discussed, but the glossary term itself does not select equipment.
| Record context | Keep visible | Why it matters |
|---|---|---|
| Generator load review | running kVA, starting kVA and load assumptions | Separates normal load from starting demand |
| kW relationship | kVA, kW and power factor | Shows how apparent and real power are connected |
| Transformer or supply note | voltage, phase and equipment data | Keeps the rating tied to the product or project source |
kVA vs kW and kVAr
kVA is not the same as kW unless the power factor context supports that relationship. It is also different from kVAr, which names reactive power.
The term should not be used as shorthand for generator or transformer approval. Equipment selection needs product data, site conditions and project review, not just a copied apparent-power value.
Using kVA in equipment records
Use the power-factor chart or kVA/kW calculator for power relationships. Use generator tools when starting kVA is part of a backup-power record, and keep the entered load assumptions visible.
