KVA to Amps

The tool computes current from apparent power (kVA) using voltage and phase configuration. It supports both single-phase and three-phase calculations, enabling quick sizing for conductors, protection devices, and feeders. The approach emphasizes correct unit handling and consistent results to improve accuracy in design reviews and educational settings. Conceptually, kVA represents apparent power S. For a single-phase system, current I = S / V. For a three-phase system, I = S / (sqrt(3) * V_LL), where V_LL is the line-to-line voltage. The tool requires S in kVA, V in volts, and the phase mode; PF is not required to derive the current from kVA. If only kW is known, users should convert to kVA using PF before calculation. Beneficiaries include electrical engineers, technicians, and students performing transformer sizing, cable sizing, and protective-device selection. The tool’s value lies in providing fast, precise ampere results without manual algebra, reducing calculation errors and saving time in field and classroom environments. Core features include explicit input validation, clear output in amperes, and consistent rounding. Typical use cases range from sizing feeders in a panel to verifying three-phase equipment ratings against system voltage and apparent power.
