Transformer size estimate

A quick kVA estimate for budgets and early layouts.

Required capacity
533.3 kVA
Next standard size
750 kVA
Full-load current, secondary
722 A

Enter the calculated demand load (CE Code, Section 8) or the measured peak demand, not the sum of connected loads. Budgetary estimate for three-phase loads. Final sizing is by the engineer of record.
