Splet01. jan. 2014 · Inter-turn short circuits in stator windings represent approximately one-third of the reported faults. Broken rotor bars and end ring faults represent around 10 percent of all induction motor faults [1] To detect the main electrical faults that occur in induction motors, most authors propose the use of the conventional Motor Current Signature ...

Splet[b] The resistor that must dissipate the most power is R 1 , as it has the largest resistance and carries the same current as the parallel combination of R 2 and the load resistor. The power dissipated in R 1 will be maximum when the voltage across R 1 is maximum. This will occur when the voltage divider has a resistive load. Thus, Spletshort-circuited turns are sought in this approach However, this technique can be applied only when the rotor is out of line. Usually, rotors have interturn short circuits only under
