Questions about used 500 kVA substation transformers
How many amps is a 500 kVA transformer?
A 500 kVA three-phase transformer carries 601 A at 480 V, 481 A at 600 V and 69.4 A at 4.16 kV at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 500,000 VA ÷ (1.732 × 480 V) = 601 A.
What 500 kVA substation transformers does Arcbarn have for sale?
Arcbarn has 8 listings, by makers including Ferranti-Packard, Delta Star and GEC Alsthom Balteau. The listed price is $1,000, and 7 are priced on request.
What tests does Arcbarn run on a used 500 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.
