9. If only available measurement equipment to you are one Volt-meter and one Amp-meter, following tests would be sufficient to estimate to find the ECD parameters. You can assume the ability to control both terminal voltage and frequency as well as shaft's speed and torque. a. 'No load test and 'Blocked rotor' test b. “No load test and 'Load' test C. 'Blocked Rotor' test and 'Load test d. All of the above 10. Induction motor rotors with built in deep bar effect have a higher starting torque b. higher operating torque C. better operating power factor d. All of the above 11. Using constant frequency supply, the induction motor magnetizing reactance Xm and core loss Rc parameters can be found by performing (circle what experiment you would do on the left hand side), using the (minimal!) set of measurement (circle what is absolutely necessary to find Xm, Ron the right hand side): (friction can be neglected) Locked rotor test No load test Rated Load test Phase Voltage, Vrms Phase Current, Arms Shaft speed, RPM Apparent Power, VA Active Power, w Reactive Power, VAR Shaft torque, Nm Power factor, Short circuit test
