Question

The measurements show that the generator supplies the rated voltage Va 8 kV and the motor speed is 1728 rev/min. ??, R2/s af For Generator Analysis 10a. Calculate the magnitude of the motor impedance. (Unit: Ohm) 26.478 Ohm You are correct. Your receipt no. is 158-3341 10b. Calculate the magnitude of current Ia. (Unit: A) 302.143 A You are correct. Your receipt no. is 158-3139 10c. Calculate the motor stator Cu power loss Pscu. (Unit: kW) 246 kW Submit Answer Incorrect. Tries 1/3 Previous Tries 10d Calculate the motor averane noower P.. fl Init,MMI

Explanation / Answer

Stator copper losses are given by 3×(current)^2×(stator resistance)

i.e. Pcu = 3×302.143×302.143×R1 = 273871.18 × R1

By substituting the R1 , we can get copper loss.

VALUE OF R1 IS NOT GIVEN IN THE POST(MAY BE CROPPED).
