Required kVA (with growth) vs Total Connected Load

Formula

## Transformer Sizing The transformer must handle the maximum demand load with adequate margin. ### Method **Maximum demand = Total connected load x Demand factor** **Required kVA = Max demand (kW) / Power factor x (1 + Growth margin)** The demand factor accounts for the fact that not all loads operate simultaneously. The growth margin reserves capacity for future expansion (typically 15-25%).

Esempio Risolto

200 kW total connected load, 80% demand factor, 0.85 PF, 20% growth.

  1. 01Maximum demand = 200 x 0.80 = 160 kW
  2. 02Required kVA = 160 / 0.85 x 1.20 = 225.9 kVA
  3. 03Select the next standard size: 250 kVA transformer.
