Convert amps to kVA effortlessly with our reliable calculator. A must-have for electrical engineers and power system analysts.
Amps: Amps measure the flow of electricity as an electrical current. Specifically, it quantifies the number of electrons passing a certain point per second.
One Ampere is defined as the current that flows with an electric charge of one Coulomb per second.
Kilovolt-amp (kVA): The unit kVA (kilovolt-amperes) is the power associated with electric current. One kilo-volt-ampere is equal to 1000 volt-amperes.
kVA is calculated as the square root of 3 (1.732) times amps times volts, divided by 1000. The volt-amp rating is the kilowatt rating determined at the unity power factor (V.A = watts / power factor).
Why kVA? The kVA rating of a device helps determine the amount of energy it can supply to the connected load. Transformers, for instance, have copper and iron losses.
The copper loss depends on current, and the iron loss depends on voltage. Neither depends on the power factor. The kVA rating is crucial for understanding these losses.
Single-phase: Comes to homes with two wires—active and neutral. The neutral wire is connected to the earth at the switchboard.
Three-phase: Has four wires—three actives (phases) and one neutral. The neutral wire is earthed at the switchboard.

The apparent power (S) in kilovolt-amps is equal to current (I) in amps times voltage (V) in volts, divided by 1000.
The apparent power in kilovolt-amps is equal to phase current (I) in amps times line-to-line RMS voltage (V L−L) in volts, divided by 1000.
The apparent power in kilovolt-amps is equal to phase current (I) in amps times line-to-neutral RMS voltage (V L−N) in volts, divided by 1000.
Converting Amps to kVA is essential for understanding the apparent power in an electrical system. It helps in sizing and rating electrical equipment accurately, especially in scenarios where the power factor varies.
Knowing the kVA rating is crucial for assessing the capacity of devices like transformers and ensuring efficient power distribution.
The calculator accommodates both single-phase and three-phase systems. Users can select the phase type (single or three) and input the corresponding current and voltage values.
The calculator then applies the appropriate formulas for each phase, providing accurate conversions in kilovolt-amperes (kVA).
Transformers have copper and iron losses, where copper loss depends on current and iron loss depends on voltage. The power factor does not influence these losses.
The kVA rating is crucial in determining the transformer's ability to handle these losses and supply power efficiently. It provides a comprehensive understanding of the transformer's capacity under various conditions.
The result in kVA represents the apparent power in the electrical system. It includes both real power (in kilowatts) and reactive power. Understanding this value is crucial for sizing generators, transformers, and other equipment.
It provides insight into the total power requirements and ensures that electrical systems can meet the demands of connected loads effectively.
