    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), 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 unsymmetrical and symmetrical faults 

    Surya, Hardi; Ismail, Daut, Prof. Dr.; Risnidar Chan Bahaudin; Muhammad Irwanto; Rosnazri, Ali; Indra, Nisja (Universiti Malaysia Perlis (UniMAP), 2010-10-16)
    Voltage sags are generally caused by faults on transmission and/or distribution systems. The voltage produced may be either unsymmetrical or symmetrical, depend on type of faults. Unsymmetrical fault is faults caused by ...
