Questions about used 72 MVA substation transformers
How many amps is a 72 MVA transformer?
A 72 MVA three-phase transformer carries 9,993 A at 4.16 kV, 3,334 A at 12.47 kV and 3,012 A at 13.8 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 72,000,000 VA ÷ (1.732 × 4160 V) = 9,993 A.
What 72 MVA substation transformers does Arcbarn have for sale?
Arcbarn has 7 listings, by makers including Hitachi, Siemens and ABB. All 7 are priced on request.
What tests does Arcbarn run on a used 72 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.
