  • SF6 Circuit Breakers - Construction, Types and Working

    The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions.

  • Conflation - GIS Wiki | The GIS Encyclopedia

    Conflation as A Gis-TechnologySee AlsoReferencesExternal LinksIn GIS, conflation is defined as the process of combining geographic information from overlapping sourcesso as to retain accurate data, minimize redundancy, and reconcile data conflicts. (quoted [Longley et al. 2001], see [Seth, Samal 2008, p129]) Horizontal conflationrefers to the matching of features and attributes in adjacent GIS sources for the purpose of eliminating positional and attribute discrepancies in the common area of the two sources. Vertical conflation solves a similar problem for GIS sources with overlapping coverage. As features are the basic entities in a GIS, the special case of feature conflation has received much attention in the published research. The data used for conflation are point, line, and areafeatures and their attributes. With conflation discrepancies can be minimized, thus improving the overall accuracy of the data sources. The goal of conflation is to combine the best-quality elements of both datasets to create a composite dataset that is be...
