    • Clamping stress effect to no load noise of single phase transformer 

      Sadanadan, Purayil Govindan (Universiti Malaysia Perlis (UniMAP)School of Electrical Systems Engineering, 2011-05)
      Single phase transformer can be sources of disturbing and annoying acoustic noise. The transformer core plays a significant role in the noise generation process. The influence of the clamping stress effects on noise levels ...

    • 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 ...

    • Standalone door access system (security base) 

      Tan, Hing Kiong (Universiti Malaysia Perlis (UniMAP)School of Electrical Systems Engineering, 2011-05)
      These days the security system is an important part for a house or premise to avoid such incident like robbery. A lot of security systems types have been apply to make sure the safety of the premise. One of them is ...

    • 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 ...
