This measurement combines both the voltage and the current without accounting for the phase angle, distinguishing it from real power measured in kilowatts (kW). Why kVA Matters for Equipment Sizing Electrical equipment such as generators, transformers, and circuit breakers are rated in kVA rather than kW.
How KVA Utilities Penalties Power Factor Impact Your Electrical Costs
kVA in Practical Applications When upgrading electrical systems or adding new machinery, engineers rely on kVA ratings to prevent overloads. Utilities often charge penalties for industrial customers with poor power factor because utilities must supply more kVA to deliver the same amount of useful kW.
You multiply the voltage in volts by the current in amperes, then divide the result by 1,000 to convert the value to kilovolt-amperes. This accounts for the phase differences in the system.
How KVA Utilities Penalties Power Factor Impact Your Electrical Costs
Kilovolt-ampere, the full form of kVA, represents the apparent power in an alternating current (AC) electrical circuit. This calculation provides the total power demand that wiring and protective devices must accommodate.
