Kilovolt-Ampere to Volt-Ampere Converter

Relationship Between Kilovolt-Amperes and Volt-Amperes

The conversion between kilovolt-amperes and volt-amperes is based on the metric system where 1 kilovolt-ampere equals 1,000 volt-amperes.

1 kVA = 1,000 VA

Therefore,

1 VA = 0.001 kVA

To convert kilovolt-amperes to volt-amperes, we multiply the value in kilovolt-amperes by 1,000 (or divide by 0.001).

For example, 1 kVA equals 1,000 VA, and 5 kVA equals 5,000 VA.

Kilovolt-Ampere (kVA)

What is a Kilovolt-Ampere (kVA)?

A kilovolt-ampere (symbol: kVA) is a unit of apparent power equal to 1,000 volt-amperes. The prefix 'kilo-' means one thousand, making the kilovolt-ampere a convenient unit for measuring larger amounts of apparent power in electrical systems.

Common Uses

• Transformers: Transformer capacity is typically rated in kVA (e.g., 50 kVA, 100 kVA, 500 kVA)
• Generators: Generator capacity is often specified in kVA
• UPS systems: Uninterruptible power supply systems are rated in kVA
• Industrial equipment: Large motors and machinery may be rated in kVA
• Power distribution: Electrical distribution systems use kVA for capacity planning
• Electrical panels: Panel ratings and load calculations use kVA

Conversion Context

Kilovolt-amperes are particularly useful when dealing with apparent power values that would be cumbersome to express in volt-amperes. For example, expressing 50,000 VA as 50 kVA is much more readable. The kilovolt-ampere unit bridges the gap between volt-amperes (for smaller systems) and megavolt-amperes (for very large power systems).

Volt-Ampere (VA)

What is a Volt-Ampere (VA)?

A volt-ampere (symbol: VA) is a unit of apparent power in an electrical circuit. It is the product of the root mean square (RMS) voltage and RMS current. Unlike watts, which measure real power, volt-amperes measure apparent power, which includes both real power and reactive power.

How Volt-Amperes Relate to Electrical Power

In AC circuits, apparent power (VA) is related to real power (W) by the power factor: Real Power (W) = Apparent Power (VA) × Power Factor. When the power factor is 1.0 (purely resistive load), VA equals W. For inductive or capacitive loads, VA is greater than W.

Common Applications

Volt-amperes are used to rate transformers, generators, UPS systems, and other electrical equipment. For example, a 500 VA transformer can handle 500 volt-amperes of apparent power. This rating is important for sizing electrical equipment and ensuring proper capacity.
