Questions about used 8400 kVA substation transformers
How many amps is a 8400 kVA transformer?
A 8400 kVA three-phase transformer carries 8,083 A at 600 V, 1,166 A at 4.16 kV and 389 A at 12.47 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 8,400,000 VA ÷ (1.732 × 600 V) = 8,083 A.
