Transmission line design. Say, I have a 1MVA generator and 2 transformers that will have the same load. What would be the proper rating of the trasformers? Is it safe to say, that I will simply divide the total rating of the generator?

4 6188When charging a 20 MVA , 33kV/6.6kV transformer through regulated (0-6.6 kV or 0-33 kV) source on no load , what will be the maximum current drawn by transformer from source and what sould be the source capacity.
TATA,
5 11546I am working on a 11KV system with fault current of 40KA for 1 second. I have selected 2500MVA 11/0.433KV transformer. How can i find the impedance value for this transformer? Please help me.

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
