    • Harmonic monitoring at UniMAP distributed campus 

      Indra, Nisja; Ismail, Daut, Prof. Dr.; Syafrudin, M.; Risnidar Chan, Bahaudin, Ir.; Surya Hardi, Amrin (Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)
      This paper an attempt has been made to monitor and analyze the harmonic distortions caused by certain typical non linear loads of an educational institution. The current and voltage harmonic distortion at PCC feeding office ...

    • 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 ...

    • Testing of contactors under voltage sag and non-sinusoidal voltage conditions 

      Surya Hardi, Amrin; Ismail, Daut, Prof. Dr.; Muhammad Irwanto, Misrun (Institute of Electrical and Electronics Engineers (IEEE), 2010-11-29)
      Sensitivity of electromagnetic contactors for voltage sags and non-sinusoidal voltage supply has been carried out by laboratory testing. Effects of sag characteristics such as; sag magnitude, sag duration and point on wave ...

    • Tracing reactive power flow and loss in electric power systems 

      Mohd Herwan, Sulaiman; Mohd Wazir, Mustafa; Omar, Aliman; Ismail, Daut; Surya Hardi, Amrin; Mohamad Suhaizal, Abu Hassan (Regional Energy Resources Information Center (RERIC), Asian Institute of Technology (AIT), 2009-03)
      This paper suggests a systematic method to trace the reactive power flow and loss named as Proportional Tree Method (PTM). From the power flow solution, the test system is modeled conceptually like a tree, where the reactive ...
