    Frequency Response

    Hi, could anybody tell me what is the stand still frequency response applied to induction motor, where can i find more information and how does it work? (the test, of course). thanks in advanced...and remember the knowledge is the power.

    cage induction machine in ATP

    greetings: dos anybody know de alternative transient program (ATP), it is a powerful tool, is probably the most widely used simulation tool for the study of transient phenomena in power systems. the question is how can i represent de induction motor in such program or where can i find somo...

    what about single phasing??

    THANK YOU ELECTRICPETE the LVUR is defined by NEMA. LVUR=(maximum voltage from average line voltage magnitude *100%)/average line voltage magnitude average line voltage mag= (Vab+Vbc+Vca)/3. this formulae looks PVUR(phase voltage unbalance rate) defined by IEEE Std. 141. With regard the...

    what about single phasing??

    Thanks Busbar, but also i ask you, how can i deduce the relation between Line Voltage Unbalance Rate (LVUR) and the magnitude of the negative sequence current. I know that this is a unsupporting condition, but stabndstill time is very low, enought ato remove a transient's earth to ground fault...

    what about single phasing??

    Hi i like to know where can i find some information about the single phasing condition in induction cage rotor machine( 3 phase). if anyone know the park's transformation aplied to the same induction motor. thanks in advance
