Questions about used 50 MVA substation transformers
How many amps is a 50 MVA transformer?
A 50 MVA three-phase transformer carries 6,939 A at 4.16 kV, 2,315 A at 12.47 kV and 2,092 A at 13.8 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 50,000,000 VA ÷ (1.732 × 4160 V) = 6,939 A.
