    Transformer KVA Conversion Calculator

    Use our Transformer kVA Calculator to determine the required kVA rating based on voltage and current. Ideal for sizing transformers in electrical systems efficiently. The Transformer in kVA Calculator serves as a utility for finding suitable kVA (kilovolt-ampere) transformer ratings according to load requirements. Transformers function as vital electrical components which require proper kVA rating determination to distribute power without excessive overload conditions. This calculator determines kVA ratings of transformers by incorporating three parameters that include load voltage and current strength alongside single-phase or three-phase phase design specifications. It generates the kVA outcome through single-phase calculations based on kVA = (Voltage × Current) / 1000, or executes three-phase kVA = (√3 × Voltage × Current) / 1000.

    Conversion using the Transformer KVA Calculation Formula

    The calculation is based on the standard formulas:

    In the case of a transformer with a single phase:

    KVA = Voltage (V) × Current (I)1000

    In the case of a transformer with a three phase:

    KVA = √3 × Voltage (V) × Current (I)1000
