Unlock Transformer group specs from desired power
Find size and voltage drop from the total needs of the installation
Guided wizard: from desired power through diversity and power factor to a specific transformer size (Sn) and max. voltage drop. All results are pure geometry on your answers plus a choice from the R5 number series (10, 16, 25, 40, 63 … kVA), which are preferred numbers and not a standard requirement — no invented recommendations.
