| Abstract | A probabilistic life model conceived for estimating the main reliability parameters of power cables operating in distorted regime is here illustrated and applied to feeder cables for power supply systems of city subways. A first key-point of this work is that reliability parameters and functions are derived by simulating the random variability of harmonic pollution according to the probabilistic limits set in EN 50160 Standard. A second key-point is that peak, shape and rms factors, which account for the effects of distorted voltage on cable life, are all considered in the reliability analysis. The application results show that even if harmonic distortion matches EN 50160 limits (in a probabilistic sense), cable life and reliability may be reduced significantly. Furthermore, among the three voltage factors, both peak and shape factors play a non-negligible role for a thorough reliability analysis |

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.
