Final answer:
The air gap power of an Asynchronous generator can be calculated by subtracting the stator losses from the input power, while the rotor ohmic losses are determined by subtracting the mechanical power output from the total power transferred to the rotor. Additional parameters are needed for complete calculation.
Step-by-step explanation:
The student's question pertains to the operation and calculation of power in a self-excited Asynchronous generator, which is a machine used in the field of electrical engineering. The problem presented involves a three-phase, two-pole, 60 Hz Asynchronous motor working at a speed of 3502 RPM, with given values for input power, terminal current, and stator winding resistance. The task is to calculate the air gap power and rotor ohmic losses, while ignoring mechanical and other losses.
To find the air gap power (Pg), we use the formula:
Pg = Pin - Pstator,
where Pin is the input power and Pstator are the stator losses, which can be calculated from I2R losses in the stator windings. Rotor ohmic losses (Pr) can be found by first calculating the total power transferred to the rotor (Pt), also known as rotor input power, and then subtracting the mechanical power output (Pm) which is Pg, as follows: Pr = Pt - Pm. However, to complete the calculations, additional data such as the rotor circuit parameters or power factor would be needed.
