The paper presents parameter testing in the transitory process of direct start-up of a synchronous motor of 4650kW/6kV used in actuating of natural gas compressors from storing stations. The electric drive motor is of synchronous type with rotational excitation and the actual operating conditions of it determine additional mechanical and electrical stresses, which can influence its performance. The asynchronous start-up mode assumed experimental determination of asynchronous start-up current values, asynchronous start-up time, excitation voltage and excitation current of exciter, voltage drop in stator winding. These experimental determinations were made using a dedicated data acquisition system. Graphical plotting was made and considered parameters were evaluated in continuous mode, then obtained values were compared with catalogue values, with conclusions being drawn for each case study.
