This paper presents the novel approach in protection and detection techniques of Alternator stator winding from the earth faults which are simulated between 2% to 10% distance point from the alternator neutral, since the impedence at that distance is very high we can not detect or protect by normal methods. The transient produced is analyzed in discreet Wavelet transforms. The potential of usin...

Faults are the most critical tectonic factors in geological structures, which have major economic impacts on mining economics. Thus it is necessary to understand faults in order to identify the actual risks and complications associated with mining. In the preliminary investigation of the Sonda-Jherruck coalfield, 3D geological modeling was not performed. The purpose of this work was to perform ...

Large–scale landslides in Valles Marineris wallrock are analyzed in order to determine what triggering mechanisms caused the landslides. These landslides occur in the locality of large faults, and therefore it is hypothesized that the landslides are the result of marsquakes triggering slope instability. This work confirms that landslides occur where the seismic hazard map forecasts highest seis...

Transverse basement (TB) faults are important structures in the mountain belts or sedimentary basins influencing various aspects of them. The origin of these faults is diverse, but their effect on the shape and configuration of continental margins is characteristics. The Western Alborz range that borders the South Caspian basin to southwest is a complex range with principal faults and known ear...

in this paper, an interval approach is presented to achieve perfect selectivity and maximum sensitivity in distance relay zones, considering uncertainties. for this purpose, first, the uncertainties affecting the settings of the three zones of a distance relay are discussed. then, by using the monte-carlo simulation, the uncertainties are modelled and the impedances seen by the distance relay a...

â  industrial site selection is a complicated decision and is related to various factors, so it is kind of multi-criteria decision analysis which is used for prioritizing different factors and selecting the best alternative among possible alternatives. in fact by scientific site selection, it is possible to minimize negative impacts of industrial construction and going towards sustainable devel...

Deregulation, increased loads, and limited resources/rights-of-way available for the building of new transmission lines are routinely pushing modern power transmission networks to operating limits. New generations of microprocessor relays provide design opportunities that help stressed transmission networks meet protection requirements. To verify that increasingly complex microprocessor relays ...

We present a fast local clustering service, FLOC, that produces nonoverlapping and approximately equal-sized clusters. The clustering is such that all nodes within unit distance of a clusterhead belongs to its cluster, and no node m units away from the clusterhead may belong to its cluster. By asserting m ≥ 2 FLOC achieves locality: effects of cluster formation and faults/changes at any part of...

introduction iran forms a relatively compact zone of active continental deformation resulted from the northward collision of arabia with eurasia during late cenozoic times, which is continuing to the present-day at a rate of 25 mm/yrs (from gps data). evidences of active tectonic in different parts of iran, has been studied and identified. the arid climate, low rates of erosion, and minimal veg...
