    • The influence of unsymmetrical AC power input to the core loss of a single phase transformer 

      Nur Azidawati Abd Razak (School of Electrical Systems Engineering, 2007-04)
      This final year project describes about the influence of unsymmetrical AC power input to the core loss of a single phase transformer. The unsymmetrical ac voltage is generated using unidirectional (half wave) ac voltage ...

    • Investigation the effect of secondary burden of current transformer (CT) 

      Siti Zaharah, Saud (Universiti Malaysia Perlis (UniMAP)School of Electrical Systems Engineering, 2011-05)
      Current Transformers (CT’s) are instrument transformers that are used to supply a reduced value of current to meters, protective relays, and other instruments. CT’s provide isolation from the high voltage primary, permit ...

    • Power transformer magnetization under different frequency supply 

      Tan, Tian Hoon (Universiti Malaysia Perlis (UniMAP)School of Electrical Systems Engineering, 2011-05)
      Transformer is a vital link in a power system which has made possible the power generated at low voltage to be stepped up to extra high voltages for transmission over long distances and then transformed to low voltages ...

    • Protections of transformers against short circuits 

      Mohd Ramli Solleh (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2007-05)
      This research focused on the protection of transformer against short circuit. Transformers are important equipment in a power system. The transformer needs to be protected from short circuit, one of the similar faults in ...

    • Single-phase transformer with symmetrical AC output 

      Nur Shahilla Abd Rahim (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-05)
      Loads connected to electricity supply systems may be broadly categorized as either linear or non-linear. Non-linear loads are any loads which draw current which is not sinusoidal. The transformer is one of the most common ...

    • Study of single phase transformer inrush current 

      Mohd Izwan, Mohd Khalid (Universiti Malaysia Perlis (UniMAP)School of Electrical System Engineering, 2011-05)
      When a transformer is initially connected to a source of AC voltage, there may be a substantial surge of current through the primary winding called inrush current. This analogous to the inrush current exhibited by an ...

    • Study of single phase transformer using QuickField and Epstein test 

      Lee Hin Keong (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-05)
      The rising generating cost of electric energy and power losses has resulted in utilities company requiring manufactures to build more efficient transformer. Therefore, energy efficient transformer will reduce cost and ...

    • Transformers design with T-joint 45º for minimum power loss 

      Mohamad Hafeeze Mohamad Nasir (Universiti Malaysia PerlisSchool of Electrical Systems Engineering, 2008-03)
      The transformer is a static device and has rotational losses. When transformers transfer power, they do so with a minimum of loss. Transformers are widely used in many sectors such as industrial sector and commercial ...
