| Abstract | The performance of electric energy distribution system is strongly affected by faults. System restoration is critical due to difficulties in searching process by the utilities maintenance crew. Usually fault searching methods employed by utilities may lead to different locations to the same fault, mainly if the feeder is dense connected. There have been many approaches in order to overcome this problem. One popular method applies short-circuits indicators to be allocated along the feeders. Nevertheless, their cost can be a limitation for the method. In this context, this work issues the problem of optimal short-circuit indicator allocation along electrical network. The allocation is optimally accomplished in order to minimize the fault searching area of the utility maintenance crew. As the the problem formulation leads to a multimodal discrete nonlinear optimization, a genetic algorithm has been the optimizer tool selected to accomplished it. The technique has been tested on a model of a feeder of an Brazilpsilas Utility. The results showed a significant improvement over ad-hoc methodologies usually adopted by utilities. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
