    • Harmonic content as the indicator of transformer core saturation 

      Ismail, Daut, Prof. Dr.; Syafruddin, Hassan; Soib, Taib; Risnidar, Chan; Muhammad Irwanto (Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
      The paper proposes a measurement method for obtaining the parameters needed to calculate a reliable indicator of the state of transformer core saturation. The major nonlinear effects in transformer core are saturation, ...

    • Investigation of power factor on harmonic effect due to types of voltage source 

      Risnidar Chan Bahaudin, Ir.; Ismail, Daut, Prof. Dr.; Syafruddin, Hassan; M. I., Yussof; Rosnazri, Ali; Dina Maizana, Maiz Ahmad; Indra, Nisja; Masykur (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      This paper discussed about power factor on harmonic effect due to types of voltage source. Usually, the voltage source is sinusoidal. But in actually, the condition of the load is has voltage sources through the elements ...

    • Simulation of flux distribution and loss calculation at three-phase transformer core with the mix 60o-45o T-joint 

      Dina Maizana, Maiz Ahmad; Ismail, Daut, Prof. Dr.; Rosnazri, Ali; Syafruddin, Hassan; Risnidar Chan Bahaudin, Ir. (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      This paper describes the result of simulation of flux distribution on 100kVA 3phase distribution transformer assembled with 23o T-joint and mitred lap corner joint with stagger yoke and limb for one lamination. The ...
