Questions about used 150 kVA dry-type transformers

How many amps is a 150 kVA transformer?

A 150 kVA three-phase transformer carries 180 A at 480 V, 416 A at 208 V and 144 A at 600 V at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 150,000 VA ÷ (1.732 × 480 V) = 180 A.
