Transformer Current Calculator

Calculate single-phase or three-phase transformer full-load current from nameplate kVA and voltage.

Transformer rating kVA Phase Voltage V

Full-load current

—A

Relationship

Three-phase: I = kVA × 1000 / (√3 × VLL)

Single-phase: I = kVA × 1000 / V

Engineering note

For three-phase systems, enter line-to-line voltage. For single-phase systems, enter line voltage.
