A method and an arrangement of identifying parameters of an induction machine when the induction machine is connected to the output phases of a voltage source inverter and the induction machine is in standstill state. The method comprises the steps of providing DC magnetization current ( i dc_magn ) to the induction machine with the inverter, controlling the power semiconductors of the inverter to off-state, controlling all the output phases of the inverter to the same potential for providing a zero voltage vector, measuring the stator current ( i sd ) during the zero voltage vector, and determining parameters of the induction machine from the stator current ( i sd ) measured during the zero voltage vector. |
