Questions about used 7000 kVA substation transformers
How many amps is a 7000 kVA transformer?
A 7000 kVA three-phase transformer carries 8,420 A at 480 V, 6,736 A at 600 V and 972 A at 4.16 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 7,000,000 VA ÷ (1.732 × 480 V) = 8,420 A.
What 7000 kVA substation transformers does Arcbarn have for sale?
Arcbarn has 3 listings, by makers including Westinghouse and Howard Industries. All 3 are priced on request.
What tests does Arcbarn run on a used 7000 kVA 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.
