      This report proposes the effect of power quality problem due to unbalance load at LV distribution system. This project aims to monitor, investigate and analyze the power quality problem due to unbalance load at selected ...

    • Effect of symmetrical voltage sags on induction motor and comparison solutions 

      Zaid, Mohd Zaini Makhtar (Universiti Malaysia Perlis (UniMAP)School of Electrical System Engineering, 2011-05)
      This final year project will analyze the symmetrical voltage sags and short interruption on the induction machines behavior: current, voltage torque and speed loss. These effects depend on several variables like sag magnitude ...

    • Lighting loads susceptibility to voltage sag 

      Ezly Azril Khalid (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-03)
      One of the common power qualities problems that are major concern in this study is called voltage sag. Voltage sag disturbances, or momentary decreases in voltage, are considered to be the most prominent power quality ...
