Why is the transformer rating is like 63 kVA, 315 kVA, 630 kVA?
I see. So, is there any kind of formula that determines which standard rating to use?
Yes, there are several factors that are taken into account when choosing a rating for a transformer. These include the voltage of the system, the load requirements, and the expected level of electrical losses in the transformer. Generally, a larger transformer will be needed for a higher voltage system or for a larger load.
