Volt-Ampere to Kilovolt-Ampere Converter

Volt-ampere (VA) is a unit of apparent power in AC electrical systems, representing the product of voltage and current. It differs from watts (real power) in AC systems where voltage and current may not be in phase.

Volt-ampere became important with the development of AC electrical systems, where the distinction between apparent power and real power became crucial. It provided a way to specify the total power capacity of AC electrical equipment regardless of power factor.

Volt-amperes are used for AC electrical equipment ratings, transformer specifications, and electrical system design. They're standard for UPS ratings, transformer capacity, and AC electrical equipment where apparent power is more relevant than real power.

Kilovolt-ampere (kVA) is a unit of apparent power equal to one thousand volt-amperes. It's widely used for rating large AC electrical equipment, transformers, and electrical systems where apparent power is the primary concern.

Kilovolt-ampere became standard with the growth of large AC electrical systems and power distribution. It provided an appropriate scale for rating transformers, generators, and large electrical equipment where apparent power capacity was the critical specification.

Kilovolt-amperes are extensively used for transformer ratings, generator specifications, large UPS systems, and electrical distribution equipment. They're standard for power system design, electrical equipment ratings, and AC power capacity specifications.
