The unsteady implementation of the conceptual model of deregulation of electric utility industry in many countries has caused significant consequences in the overall health of the general population of large power transformers [LPTs]. LPTs are now subject to adverse conditions…

Pipeline tubes are part of vital mechanical systems largely used in petrochemical industries. They serve to transport natural gases or liquids. They are cylindrical tubes and are submitted to the risks of corrosion due to high PH concentrations of the…

This paper considers the solution of fully fuzzy linear system (FFLS) by first reducing the system to crisp linear system. The novelty of this article lies in the application of Gauss elimination procedure with implicit partial pivoting to FFLS. The…

This paper presents the various advantages of Thyristor Controller Series Capacitor (TCSC), both as a Power Flow Controller, as well as a Short Circuit limiter during faults. The results have been derived and verified from the software PSCAD, and the…

The Schmitt Trigger is a comparator circuit that incorporates positive feedback. Noise is being ignored by CMOS Schmitt Trigger as the hysteresis in a Schmitt Trigger circuit offers a better noise margin and noise stable operation. And the simulation has…

The main objective of a soft switching circuit is to reduce the switching losses in a static converter when is switched at high frequency. In this paper a DC link fuzzy logic controller applied to a VSC (voltage source converter).…

This paper considers the concept of very advanced technologies being developed in the West, to solve rural electrification problems in the developing world. The myth that poor quality is cheaper and therefore more affordable for rural electrification is dispelled. On…

The 21st Century Power Transformer is produced by combining modern high voltage cross-linked polyethylene (XLPE) cable technology with conventional transformer. The technique of solid insulation is adopted in the new dry transformer so that the pollution from leakage of insulating…

Cleaning work can be physically demanding and a need has been identified to developed methods for systematic ergonomics evaluation of new products. Upon a manufacturer’s initiative an evaluation programme was devised to appraise a modified design of single disc floor…

This paper proposes a 3T XOR gate design consisting of pMOS transistors. This new design of XOR cell has been compared with existing 3T XOR design and significant improvement in PDP (Power-Delay Product) has been obtained. As an application of…
