Mitigation of switching effects on induction motor under star-delta scheme based energy conservation

Enhancement of cost effective energy conservation technology plays a vital role in process industries. Hence acquiring star-delta based energy conservation scheme for induction motors is common in industries. But the impact of transient and vibration during switchover are the main hindrance of the star-delta based energy conservation scheme. Thus, analyzing the effect of transient and vibration is mandatory for predicting the machine´s life and to provide proactive solution to mitigate these upshots. Therefore, this paper analyzes the effects of switching and excogitated the mitigation technique (an economically best strategy). In additional to this, the relative analysis is carried out between existing energy conservation scheme and the proposed strategy.
