Questions about used 3750 kVA substation transformers
How many amps is a 3750 kVA transformer?
A 3750 kVA three-phase transformer carries 4,511 A at 480 V, 3,608 A at 600 V and 520 A at 4.16 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 3,750,000 VA ÷ (1.732 × 480 V) = 4,511 A.
