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 · 7,251 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 · 7,187 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 · 7,679 accessesView PDF Cite
