Abstract: A method and arrangement for determining leakage inductances of a double fed induction generator, DFIG, (10) wherein, in response to the stator current of the DFIG being equal to or below a first predetermined threshold, values of a stator voltage, a rotor voltage and a rotor current of the DFIG are determined, and a rotor leakage inductance of the DFIG is calculated on the basis the determined values, and, in response to the rotor current of the DFIG being equal to or below a second predetermined threshold, values of the stator voltage, the rotor voltage and the stator current of the DFIG are determined, and a stator leakage inductance of the DFIG is calculated on the basis of the determined values.
