Questions about used 4000 kVA substation transformers
How many amps is a 4000 kVA transformer?
A 4000 kVA three-phase transformer carries 4,811 A at 480 V, 3,849 A at 600 V and 555 A at 4.16 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 4,000,000 VA ÷ (1.732 × 480 V) = 4,811 A.
What 4000 kVA substation transformers does Arcbarn have for sale?
Arcbarn has 9 listings, by makers including Ferranti-Packard, Niagara Transformer and Northern Transformer. The listed price is $115,200, and 8 are priced on request.
What tests does Arcbarn run on a used 4000 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.
