Inputs to prepare
Enter balanced three-phase kVA and line-to-line voltage, or enter voltage and measured line current. Confirm that the units match the project.
GENKVA factory calculator
Three-Phase Current Calculator
Convert three-phase kVA, voltage and current for a balanced system.
Estimate line current from kVA and line-to-line voltage, or calculate kVA from measured current.

What the result means
The result uses the square-root-of-three relationship for a balanced three-phase system and shows calculated amperes or kVA.
How to use it
Use this estimate for early cable, breaker or load discussions only. Final conductors and protection require applicable-code calculations by a qualified engineer.
Method and limits
A useful estimate, not a final equipment selection.
We show the calculation and keep the inputs visible. Complex loads, harmonics, voltage and frequency dip, load steps, altitude, temperature and exact machine data can change the final result.
For critical systems, motor-rich loads or final procurement, send the result to our factory and have the complete power system reviewed by qualified engineers.
