    • Adjustable speed drives susceptibility to voltage sag 

      Mohd Hasrul Mohd Kamaruzzaman (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-05)
      Voltage sags are probably the most important power quality problems affecting industrial and large commercial customers. These events are usually associated with a fault somewhere on the supplying power system. The ...

    • Contactors and relays susceptibility to voltage sags 

      Mohd Yazid Zaimuri (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-03)
      A contactor is electrically controlled switch used for switching a power circuit and activated by a control input which is a lower voltage or current than that which the contactor is switching. While a relay is an ...

    • 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 ...

    • Over current protection simulation for voltage sag in power system 

      Hafizan, Jaladudin (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2007-03)
      Voltage sags have become one of the major power quality concerns in recent years facing customer. Characteristics of voltage sags caused by faults in transmission and distribution networks depend on the over current ...

    • Programmable Logic Controller (PLC) susceptibility to voltage sag 

      Mohd Reza Mohd Mohyin (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-05)
      Programmable logic controller or PLC is the most commonly used industrial automation technique in the world. It is universally applied for factory automation, from the creation of computerized versions of relay. It is used ...

    • Sensitivity of adjustable speed drive to voltage sags and solution 

      Nur Atikah, Zainol (Universiti Malaysia Perlis (UniMAP)School of Electrical Systems Engineering, 2011-04)
      This project was discuss a about sensitivity of adjustable speed drive to voltage sags and solution. This project is presence the three phase (balance or symmetrical) and single phase ASD and the result from the experimental ...

    • Simulating of Voltage Sag caused by fault in power system 

      Mohd Khalid Mat Noh (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-03)
      The voltage sag phenomenon is the most severe power quality problem that exists today. Electrical engineers have placed the issue of power quality studies on high priority due to the economic loss resulting from voltage ...

    • Voltage sags and interruptions in a distribution system 

      Nur Zahirah Mohd Ali (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-05)
      Voltage sag is the important factor in power quality problem faced by many industrial customers. The most frequently reported among various types of power quality disturbance are voltage sags. The disturbance will cause ...
