The capacity of a transformer depends on its rated voltage
and current. The load current varies depend on the voltage
of the transformer.
If this 3 phase 2000KVA has a primary voltage @ 4160V, then
the primary current is 278A (2000000/1.73/4160V)
If the secondary of this 2000KVA is 480/277 then the
secondary full load current is 2408A (2000000/1.73/480).
If the secondary of this 2000KVA is 208/120 then the
secondary full load current is 5558A (2000000/1.73/208).
