Electricity Distribution System using Geospatial Technology – A Case Study for Hosur Town, Krishnagiri District

Utility services are an important component of the physical structure of towns and there is a need for detailed information about the location and condition of their infrastructure. Acquiring data in the conventional way is time consuming and costly. The integration of GIS with electric utilities is tremendously improving the planning and operation of the system. GIS and GPS are also integrated for mapping and analysis of electric distribution system. In the present paper, the location of each distribution transformer in the Hosur town was collected using GPS. Hosur town was delineated from the satellite image using the GIS technique. Survey of India toposheets and satellite imageries are used to prepare various thematic layers viz landuse/landcover map, transportation network map. The solar radiation on the rooftop of each building was determined using the solar radiation tools in the arctool box of ArcGIS. The thematic layers were finally integrated into ArcGIS software to estimate the regions that are prone to high solar radiation for the installation of Photo Voltaic panels.
