Questions about used 25 MVA substation transformers
How many amps is a 25 MVA transformer?
A 25 MVA three-phase transformer carries 3,470 A at 4.16 kV, 1,157 A at 12.47 kV and 1,046 A at 13.8 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 25,000,000 VA ÷ (1.732 × 4160 V) = 3,470 A.
What 25 MVA substation transformers does Arcbarn have for sale?
Arcbarn has 5 listings, by makers including Federal Pacific, Federal Pioneer and Ferranti-Packard. All 5 are priced on request.
What tests does Arcbarn run on a used 25 MVA substation transformer?
Every unit is tested before it ships: turns ratio (TTR) on every tap; insulation resistance; winding resistance; power factor and capacitance; oil sample: dissolved gas analysis and dielectric strength; tap changer inspection and operation. You see the report before you buy.
