630kva dry-type transformer rated current is how much
Low pressure side is about the capacity multiplied by 1.5, depends on how much you can count the high pressure.
If it is a 10kV transformer,
Then the rated current = 630 / 10.5 / √3 = 34.64A, which refers to a current, phase current
Hello there:
- ★ 1, the transformer current calculation formula is: transformer capacity ÷ (rated voltage × root number 3)
- ★ 2,630kva transformer primary current: 630kva ÷ (10kv × 1.732) = 36.37A;
- ★ 3,630kva transformer secondary current is: 630kva ÷ (0.4kv × 1.732) = 909A.
