    • The effects of harmonic components on transformer losses of sinusoidal source supplying non-linear loads 

      Ismail, Daut; Syafruddin, Hasan; Rosnazri, Ali; Samila, Mat Zali; Haziah, Abd Hamid (Science Publications, 2006)
      An important consideration when evaluating the impact of harmonics is their effect on power system component and loads. Sinusoidalare major components in power systems. The increased losses due to harmonic distortion can ...

    • Harmonic performance of single phase transformer with DC biased 

      Syafruddin, Hasan; Ismail, Daut, Prof. Dr.; Soib, Taib, Prof. Madya Dr.; Dina Maizana, Maiz Ahmad, Ir.; Rosnazri, Ali; Nor Ashbahani, Ashbahani (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      Direct current (DC) flowing through the earthed neutrals of transformer windings causes a DC component in magnetizing current. Owing to nonlinearity, the waveform of this current is strongly distorted. A high enough ...

    • Induction motor behavior due to symmetrical and un-symmetrical faults 

      Ismail, Daut, Prof. Dr.; Surya Hardi, Amrin; Tunku Muhammad Nizar, Tunku Mansur; Syafruddin, Hasan; Indra, Nisja; Mohd Hafizi, Idris (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      This paper presents induction motor behavior caused by symmetrical and unsymmetrical faults. PSCAD/EMTD power system simulation was used for a simple model and the investigation purpose. Voltage sags are generally caused ...

    • Investigation of influence of voltage source type on harmonic characteristics 

      Risnidar, Chan Bahaudin; Ismail, Daut, Prof. Dr.; Surya, Hardi Amrin; N., Hashim; Indra, Nisja; Syafruddin, Hasan (Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
      This paper discussed about influence of voltage source types on harmonic characteristics. Usually, the voltage source is sinusoidal. But in actually, the condition of the load is has voltage sources through the elements ...

    • Investigation of rolling and hard direction of magnetic field distribution on Grain Oriented M5 electrical steel material 

      Ismail, Daut; Anayet, Karem; Syafruddin, Hasan; Muhammad Irwanto (Universiti Malaysia Perlis, 2009-10-11)
      This paper describes the idea of the electrical machine design perspective whose aim is latter on to design and development of the copper and aluminum rotor for induction motors to improve the operational efficiency. The ...

    • K-factor due to implementing of DC unbalanced/balanced of a transformer 

      Syafruddin, Hasan; Ismail, Daut, Prof. Dr.; Soib, Taib, Assoc. Prof. Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2007-12-04)
      This paper presents the effects of harmonic distortion on loaded single phase two winding transformer.The impact on K-factor is studied by implementing DC unbalanced and balanced configurations. The measurements are done ...
