The negative sequence current can offer an efficient and fast monitoring technique to detect incipient stator fault in induction machines. However, unbalanced supply voltage, inherent machine asymmetry and non ideal sensors can also contribute to the generation of this negative sequence current. Thus, it is rather difficult to extract the negative sequence current caused only by the fault. To improve the accuracy of fault detection, this paper proposes an efficient method based on the use of… CONTINUE READING
