Apparent Power Converter - VA, kVA, MVA and More

Convert apparent power between different units. Fundamental for sizing transformers, generators, and electrical power systems.

What is apparent power?

Apparent power is the product of voltage and current in AC systems, measured in VA (Volt-Ampere). It represents the total capacity of the system, combining active power (watts) and reactive power (VAR).

Units of apparent power

Convert between VA, kiloVA (kVA), megaVA (MVA), and other units. Transformers and generators are specified in kVA or MVA according to their capacity.

Transformer sizing

Transformers are sized in kVA, not kW, because they must provide total power regardless of the load power factor. Conversions facilitate correct specification.

Electric generators

Generators are also specified in kVA. Conversions help choose the appropriate capacity, considering the expected power factor and the necessary safety margin.

Relationship with Active Power

Apparent Power (VA) = Active Power (W) / Power Factor. Conversions facilitate demand calculations, sizing, and energy efficiency analysis.

Applications in UPS

UPS (uninterruptible power supply) systems are specified in VA and W. Conversions help choose suitable equipment, considering load type and power factor.

Electrical Infrastructure

Planners use apparent power conversions to size substations, calculate network capacity, plan expansions, and ensure adequate supply.

Conclusion

Convert apparent power accurately using our tool. Essential for engineers who size and manage electrical power systems.
