Questions about used 2500 kVA substation transformers

How many amps is a 2500 kVA transformer?

A 2500 kVA three-phase transformer carries 3,007 A at 480 V, 2,406 A at 600 V and 347 A at 4.16 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 2,500,000 VA ÷ (1.732 × 480 V) = 3,007 A.
