Comparison of losses and flux distribution in 3 phase 100 kVA distribution transformers assembled from various type of T-Joint geometry
(Science Publications, 2006)
This paper describes results of an investigation of the variation of power loss, building factor, flux leakage and flux distribution in 3-phase model transformer cores assembled from various type of T-joint geometry. The ...
Design of a single-phase rectifier with improved power factor and low THD using boost converter technique
(Science Publications, 2006)
The 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 ...
Characteristic Curve of a Fuel Cell
(Science Publications, 2006)
The aim of this study was to deliver information about the features of fuel cells. It cover analysis of theory and experiment done using a set of tool called Hydro Genius Teach. The experiment is about investigating the ...
The effects of harmonic components on transformer losses of sinusoidal source supplying non-linear loads
(Science Publications, 2006)
An important consideration when evaluating the impact of harmonics is their effect on
power system component and loads. Sinusoidalare major components in power systems. The increased losses due to harmonic distortion can ...
Simplification of sun tracking mode to gain high concentration solar energy
(Science Publications, 2007)
Power 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 ...
Computer designed solar concentrator
(International Association of Science and Technology for Development (IASTED)/ACTA Press, 2007)
This paper discusses a computer designed optical concentrator, which is providing efficient solar energy transfer to a Stirling Engine. The receiver can make line focusing onto the absorber of Stirling engine located at ...
Tracking error analysis of a rotation-elevation mode heliostat
(Science Publications, 2007)
For 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 ...
Evaluation of transformer magnetizing core loss
(Asian Network for Scientific Information, 2006)
Loss in transformer core is the electrical power lost in terms of heat within the core of transformer, when core is subjected to AC magnetizing force. It is composed of several types of losses such as Hysterics loss, eddy ...
Tracing reactive power flow and loss in electric power systems
(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 ...
