I'm sizing a transformer for a generator system for our TV and FM stations. The loads vary, everything from tower lights to HVAC systems. The primary side of the transformer is 480V, the secondary will be 208/120. And with everything running, Phase A is pulling 188 amps, B is pulling 186.2 amps, and C is pulling 203.7 amps. Do you just add the currents to calculate KVA, or is it the average of the currents to calculate KVA?
