I have a question about electricity

How many KW of motors can a 315KVA transformer drive? When calculated using formulas, various results are obtained – 270KW, 230KW, and so on. In practice, it is possible to drive 10 motors of 30KW each. Could those of you in this field provide the correct calculation formula or result?
Generally, a 10% load margin should be reserved for transformers, but the equipment should not be started all at once; instead, larger equipment should be started first followed by smaller ones, with the load being increased gradually.
Different motors have different power factors, considerations regarding the phase factor, and whether capacitive compensation should be set at 0.9 or 0.95, among other things. . . There are many things to consider during the design process. I recommend that you take a close look at the \"Manual for Industrial and Civil Power Distribution Design\"; it contains formulas, which can be found in the first 1/3 of the book. The latest edition should have a black cover.
