Effect of Voltage Sag on an Induction Motor IJTSRD
The aim of this paper is to analyze the performance of the three-phase squirrel cage induction motor under various voltage fluctuation levels. Generally, Induction motor drives are preferred for its simple and easy control. Their performance depends on relative power supply quality such as voltage sag, harmonics, voltage unbalance and voltage fluctuations. The induction motor […]
