Actually why the transformers are rated in KVA.?

Answer Posted / kanchan kumar

This is becoz variable loss i.e copper loss is proportional to current and fixed loss i.e iron loss is proportional to voltage hence by combinig the both losses it will be product of current and voltage hence that is why rating is in VA ie due to high value it is in KVA

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
