| Abstract | Major advantages of compensated networks are the self-extinction of arcing faults and that the RMS of the single phase to ground (SPG) fault current is small, and therefore the fault can theoretically be allowed to persist for several hours. The continuous operation of the system can be sustained during a SPG fault in order to continuously supply the consumers if the touch voltage at the poles remains small. A great disadvantage of compensated networks, however, is the complicated way a SPG fault can be located. The first part of this paper contains a short review on problems related to distribution system operators' (DSOs) current practice regarding Earth fault location and sustained faulty operation of compensated networks. Some fault localization methods published in the literature will then be shortly summarized and compared based on computer simulation using EMTP software. Advantages and disadvantages of different methods will be shown. An innovative device and method will be presented that was implemented at two Hungarian DSOs. An evaluation of the operation experience will be given based on real field measurement data. The main contribution of the paper is the proposal for a fault location method that greatly increases system reliability indices and is therefore economically feasible in most distribution systems. |

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.
