Questions about used 66 MVA substation transformers
How many amps is a 66 MVA transformer?
A 66 MVA three-phase transformer carries 9,160 A at 4.16 kV, 3,056 A at 12.47 kV and 2,761 A at 13.8 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 66,000,000 VA ÷ (1.732 × 4160 V) = 9,160 A.
