| Abstract | Single-phase-earth arcing faults constitute the largest proportion of faults on non-effectively grounded system. And arc self-extinction behavior is involved determining the neutral grounding mode in such system. Peterson coil compensated system in the paper refers to power system of neutral with Peterson coil compensating the network currents. The extinction and the re-ignition of arc are determined by the competition between the recovery voltage and the dielectric recovering strength of arc channel. In general, the insulation strength is the intrinsic characteristics of the arc channel. And the peak value and the rising rate of recovery voltage in the fault phase would be reduced with Peterson coil. Lots of laboratory tests under arcing faults are performed in 10 kV distribution network. Test circuit is set up, and taking arc films with the high-speed video camera. Distributions of arc duration times are derived, extracting arc self-extinction features. Further, arc self-extinguishing probability is computed and therefore proposes the limit value of the residual current on Peterson coil compensated system. The test results have validated the effective compensation of Peterson coil and the over-voltage restriction by the neutral resistor. |

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.
