why is the rating of transformer done in kva and not in kw.
Answer Posted / manoj-essar
dear manoj, there is no concern of static or rotating
device, then why r u saying in this way?
Trafo is not having unity pf but it depends upon load type
of trafo...(inductive or capacitive or resistive load)

What is the rating of a circuit breaker needed for 300 kv load in 33KV supply line of 33/415 transformer ? Whether 800/1200 amp vaccum circuit breaker can perform for a 33 KV line in input in 415 volt in output of the transformer ?
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
