The following test data apply to a 110 kVA, 2300 V three-phase four-pole 60 Hz induction motor.
No load test at rated voltage and frequency: Load current = 8.1 A, Three-phase power = 3025 W
Blocked-rotor test at rated current and 15 Hz: Line voltage = 268 V, Three-phase power = 10.2 kW
Stator resistance between line terminals = 2.34 Ω.
Compute the stator current and power factor, kW output, and
efficiency when this motor is operating at rated voltage and
frequency with a slip of 2.8 percent.
