| Abstract | Based on the arc mathematical model for the SF6 circuit breaker (CB), the equations describing the arc chaotic behavior were deduced by considering the velocity and temperature effect in the model as the chaotic characteristics and expending in 2D form using the convergence of Fourier series. The time series, and Lyapunov exponents diagram reflecting the chaotic behavior of arc were obtained based on the numerical analyses, which proved that the arc behavior exist chaos during the arc quenching. In order to reflect the interactions of the coupling of the electric field, magnetic field and gas flow field and confirm the factors affecting the arc chaotic behavior, third-order nonlinear differential equations with constant coefficient for arc in SF6 CB has been obtained by introducing Maxwell and current density equations in the arc mathematical model and linearizing a set of nonlinear differential equation for the arc model according to the stability theory. The results show that the shock wave is one of the origin of the arc instability. By adjusting the parameters for SF6 CB closely related to the temperature, the system has significant chaotic behavior, which indicates that the system stability can be effectively controlled according to the temperature. |

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.
