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 ...

This paper describes the idea of the electrical machine design perspective whose aim is latter on to design and development of the copper and aluminum rotor for induction motors to improve the operational efficiency. The ...
Comparison between the localized power loss and flux distribution in a three phase distribution transformer 100 kva assembled from various type of T-joint geometry with Staggered Yoke
(ACTA Press, 2008-04-02)
This paper describes the result of an investigation of the variation of localized power loss and flux distribution in 3-phase transformer cores 100kVA assembled from various types of T-joint geometry. The localized power ...
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 ...

Measurement of flux density distribution on 100kVA 3-Phase distribution transformer assembled with 90° T-joint and mitred lap corner joint with stagger yoke by using search coil
(Institute of Electrical and Electronics Engineers (IEEE), 2008-12-01)
This paper describes the result of measurement of flux distribution on 100kVA 3phase distribution transformer assembled with 90° T-joint and mitred lap corner joint with stagger yoke. The measurement involves the variation ...
Power quality and electromagnetic compatibility -The 'simple or not so simple' ubiquitous power supply input stage -
(Institute of Electrical and Electronics Engineering (IEEE), 2008-12-01)
Power Quality is per se the ac line input voltage quality that in turn is determined by the interaction of the source impedance and the line current. Low frequency line current harmonics up to the 40th harmonic (2 kHz for ...
Investigation on the effect of shunt capacitor and shunt filter on harmonic in distribution system
(Institute of Electrical and Electronics Engineering (IEEE), 2008)
Nowadays nonlinear loads are widely used in many consumer equipment and power systems. The main problem in using of nonlinear loads is harmonic distortion. This paper will discuss the effect of application of shunt capacitor ...
