Questions about used 69 MVA substation transformers
How many amps is a 69 MVA transformer?
A 69 MVA three-phase transformer carries 9,576 A at 4.16 kV, 3,195 A at 12.47 kV and 2,887 A at 13.8 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 69,000,000 VA ÷ (1.732 × 4160 V) = 9,576 A.
