| Abstract | In a DBD it is not possible to measure the electrical values of the plasma directly. To determine them it is necessary to separate the capacitive from the real current component within the gap. To overcome this problem Liu and Neiger have published an analytical method to determining the plasma values from the lamp voltage and current. This method is very complex and needs some simplification to differentiate and integrate the voltage and current values over time so that a real time analysis is not possible. Based on this model, Roth and Schwarz developed an electrical setup to measure the inner values directly. We have developed this method further and have now the possibility to determine the plasma voltage, current for pulsed operation. Based on this measurement method we have developed an electrical model to describe the role of space charges inside the gap. With the model it is possible to amount the electrical field of space charges integrated as voltage $u_{charge}.$ The difference between the determined voltage $u_{charge}$ and the measured gap voltage describes the effective exciting voltage $u_{excite}.$ Examples of sinusoidal and pulsed excitation show that this model could describe the development of space charges correctly. The new defined ignition voltage $u_{excite,max}$ shows, despite the old definition of $u_{gap,max},$ no dependence on the voltage waveform and describes the behavior of preionization correctly. |

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.
