Questions about used 300 kVA dry-type transformers
How many amps is a 300 kVA transformer?
A 300 kVA three-phase transformer carries 361 A at 480 V, 833 A at 208 V and 289 A at 600 V at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 300,000 VA ÷ (1.732 × 480 V) = 361 A.
