Abstract | An engineering model for electrical simulation of one-dimensional reactor-pulse generator system accounting for salient features of pulsed corona (PC) discharge has been developed. The following assumptions lay the basis for the model. (1) The discharge gap before the streamers have crossed it divides into two parts. The first one is the space between the inner electrode and the expanding streamer front. Between the streamer front and the outer electrode is the second part, where the displacement current flows. (2) The "streamer part" is simulated as a conducting area. The streamers propagate to the outer electrode with velocity that depends on the average field and polarity. After the gap has been bridged, it is modeled as a fixed resistor. Power circuits of inductive and capacitive pulsers coupled to coaxial reactors were modeled on the PSpice platform using its analog behavioral modeling capabilities. Typical timing diagrams and volt-ampere characteristics are presented. The model yields realistic values and behavior of current, voltage, power and energy that are in fair agreement with experimental data obtained with an inductively based nanosecond pulser. It was found that a relatively small energy share is coupled to the "streamer part" of the gap. More is wasted in dissipative and reactive components of the circuit. To optimize the system it is suggested to match the rector and the pulser in such a way as to deposit the energy into the gap before the primary streamers have crossed it. |

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.
