| Abstract | A general survey is presented of the nature and distribution of failures and interruptions due to lightning upon the circuits of a large city supply system. Recommendations are given for improving conditions without specifying particular makes of arresters, in recognition of the fact that a considerable number of different types is proving adequate to meet the conditions imposed upon them on the moderate voltage systems under consideration. The subject is treated under three principal divisions: 1st. Troubles on 115-230 volt distribution circuits. 2nd. The 2300 volt circuits, and 3rd. The 13,200 volt circuits. It is shown that line failures on the low-voltage circuits are so infrequent as to be practically negligible, and that the blowing of fuses and injuries to other parts of the equipment on customer's premises are infrequent except in the case of house meters. A considerable number of meter burn outs are recorded, and it is shown that trouble from this source increases with the length of the secondary circuit. To guard against future trouble, especially as secondary networks are developed, it is recommended that a simple spark gap or other equivalent type of arrester be installed at the customer's premises as a part of the equipment in his service box. For the 2300 volt circuits, it is found that lines which run over high ground and open country are more exposed to transformer burn outs and the blowing of transformer fuses than lines in the built-up sections where buildings screen the circuit. |

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.
