| Abstract | The determination of the maximum value $(T_{MAX})$ of the anticipated per-unit transient overvoltage factor (T) used to establish the maximum anticipated transient overvoltage magnitude $(TOV_{MAX})$ for use during energized work, requires evaluation of the connected system components and control mechanisms available. This evaluation process should consider the various causes and control of T as well as the probability of a triggering event occurring. Knowledge of T, determined for the system conditions at the time of energized work, will allow the appropriate controls to be used for the system and at the work site to safely perform the task. One of the most important factors that determine maximum T is the magnitude of the trapped charge on the line after opening of circuit breakers at both ends. The purpose of this paper is to suggest criteria for an engineering evaluation of the causes and controls of T for calculation of the minimum air insulation distance (MAID) for use during energized work. Methods for reduction of the trapped charge are also discussed. |

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.
