Using the data given in Problem, estimate the difference in your calculations if the Thévenin equivalent circuit was used rather than the more approximate model given by the straight values when Rm = 29.82 Ω and Xm = 52.0 Ω. Express the final differences in percentage terms.

Problem

Calculate the necessary torque of a primary machine and the maximum rated power of an IG fed at 6.0 kV, 60  Hz, 4 poles, R1 = 0.054 Ω, R2 = 0.004 Ω, X1 = 0.852 Ω, and X2 = 0.430 Ω. What is the rated mechanical power? Calculate the distribution transformer ratings if the subtransmission voltage is 69 kV.
