Total Power Requirement (with Growth Factor) = Total Power Requirement x (1 + Growth Factor) = 59 kVA x (1 + 0.3) = 76.7 kVA. So the total power requirement with growth factor is 76.7 kVA. Now that you have determined the total power requirement, you can select a transformer that is capable of providing the necessary power.

The total KVA the transformer must supply for four single-phase heaters is: 12amps ×480volts×4 1000 =23KV A 12 a m p s × 480 v o l t s × 4 1000 = 23 K V A. The total KVA is: 112 KVA + 23 KVA = 135 KVA. A three-phase transformer of this size, however, would be able to supply 135 KVA ÷ 3 = 45 KVA per phase.
