Questions about used 750 kVA substation transformers
How many amps is a 750 kVA transformer?
A 750 kVA three-phase transformer carries 902 A at 480 V, 722 A at 600 V and 104 A at 4.16 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 750,000 VA ÷ (1.732 × 480 V) = 902 A.
