| Abstract | It is well known that thermal and electrical stresses have a strong influence on the degradation of insulation, but the effect of the stress duration is not yet well analysed. On this account thermal, electrical, and a combination of thermo-electrical stresses were applied to a number of cast-resin samples, and their effects were evaluated via partial discharge measurements. Stress duration as well as time without stress was varied. This information will be used in a statistical method to recognise the influence of the duration of the applied stress on the partial discharge activity of every sample. The statistical method is the analysis of variance (ANOVA), which is useful when the frequency distribution of the measurements is a so-called normal distribution. All measurements were carried out following this distribution and thus the reliability of such tests is only dependent on the linear behaviour of the following variables: partial discharge inception and extinction voltage, number of discharge impulses, sum of the charges of all impulses, and average charge per impulse. The other variables are the stress duration and the time without stress. In order to recognise variations which only correspond to the same effect, tests must be ordered in groups with the same characteristics. Tests must also be performed in continuous and repetitive cycles under stress in order to avoid undesirable effects. The results of these experiments may form the basis for the identification of a relationship between one or more partial discharge parameters and the stress duration |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
