What this rating is
5000 kVA, or 5 MVA, is around the upper limit of what is built as a pad mounted unit. Above this the equipment becomes a substation transformer with separate switchgear and different clearance rules.
About 6,014 amps at 480 volts, which is why units this size are frequently specified with a higher secondary voltage such as 4160 volts to keep the secondary conductors manageable. It is the largest rating Giga Energy builds in Houston.
Common questions
How many amps is a 5000 kVA transformer
About 6,014 amps at 480 V three phase. About 694 amps at 4160 V three phase. About 231 amps at 12470 V three phase. Three phase current is kVA times 1000 divided by the voltage times the square root of three. Single phase leaves out the square root of three, which is why the single phase figures are much higher.
What is a 5000 kVA transformer used for
5000 kVA, or 5 MVA, is around the upper limit of what is built as a pad mounted unit. Above this the equipment becomes a substation transformer with separate switchgear and different clearance rules.
Is a 5000 kVA transformer pad mounted
Yes. We quote this rating. It sits at the boundary between distribution and substation equipment.
