A 500kW, 2400V, four-pole, 60Hz, Y connected induction machine has the following equivalent circuit parameters in ohms per phase referred to the stator: R1 = 0.122Ω; R2 = 0.317Ω; X1 = 1.364Ω; X2 = 1.32Ω; Xm = 45.8Ω; Rc≈∞ (no core losses) When operating as a motor, supplied from a 2400V source, the machine achieves rated shaft output power (500kW) at a slip of 3.35%. The machine is to be used as a generator, driven by a wind turbine. It will be connected to a distribution system which can be represented by a 2400V infinite bus. a) From the given data calculate the total rotational losses at rated load
