Question

From no-load and block-rotor tests on an induction motor :

no-load test gives the stator circuit parameters, block-rotor gives the rotor circuit parameters

no-load test gives the information about exciting current and rotational losses, Block-rotor test gives information about leakage impedance

no-load test gives the rotor circuit parameters, block-rotor gives the stator circuit parameters

no-load test gives the information about leakage impedance and block-rotor test gives the information about exciting current and rotational losses

Explanation / Answer

Solution: - The no load test on an induction motor gives information with respect to exciting current and no-load losses. A blocked rotor test is normally performed on an induction motor to find out the leakage impedance.

Hence correct option is no-load test gives the information about exciting current and rotational losses, Block-rotor test gives information about leakage impedance.
