Transformer Sizing Calculator
Estimate the distribution transformer rating (kVA) your building needs from its connected load, diversity and growth margin. Adjust the inputs, then get an engineered electrical design from our team.
Your load
Estimates maximum demand = connected load × diversity, then converts to kVA at your power factor and adds margin. Motor inrush and harmonics may need a larger unit.
