Research ArticleOpen accessIn the author namesTracking Error Analysis of a Rotation-Elevation Mode HeliostatOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanFor the past few years, great efforts have been done in improving the tracking accuracy of a newly proposed rotation-elevation tracking mode heliostat. A special simulation program has been developed to systematically analyze the image movement and to find out the error of the parameters. In the simulation program, ray-tracing method was applied to work out the central point position … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,255 accessesView PDF Cite

Research ArticleOpen accessIn the author namesSimplification of Sun Tracking Mode to Gain High Concentration Solar EnergyOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanPower conversion from solar thermal energy to electrical energy is still very cost-intensive. Serious effort has to be given in the development of the concentrator or heliostat structure expenditure which contributing the most expensive component in a central receiver solar power plant. With current development to find alternatives and lower down the capital, a new mode of sun tracking has … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,190 accessesView PDF Cite

Research ArticleOpen accessIn the author namesDiagnosis of MV Oil Filled Cable Terminations with X-Ray Imaging and Infrared (IR) ThermographyMohd. Rafi Adzman, Ismail Daut, Muzamir Isa et al.A main purpose of doing a diagnostic in cable system including its accessories such as impregnated paper insulated oil filled cable termination is to predict failure before they occur. Those cable and accessories, which are about to fail, can be replaced, thereby reducing the incidence of electrical system failure, thus reducing the electricity outages. This paper presents the work carried … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,682 accessesView PDF Cite

Research ArticleOpen accessIn the author namesDesign of a Single-Phase Rectifier with Improved Power Factor and Low THD using Boost Converter TechniqueIsmail Daut, Rosnazri Ali, Soib TaibThe method of using Boost type of converter was proposed for a 300W single-phase rectifier in this paper. By designing the necessary techniques and methodology, the overall Power Factor (PF) and Total Harmonic Distortion would be improved to the expectation. The cause of having low PF and high THD for a diode-capacitor type of rectifiers is related to non-linearity of … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 7,132 accessesView PDF Cite
