OpenFlow/Software-Defined Networking (SDN) is a new networking paradigm that virtualizes network infrastructure by decoupling the control and data plane logic of traditional network devices. The controller of SDN has the overall look about network topology and hence provides flexibility to network operators to implement its own routing approaches. However, it could not control the way client works...
The grounding grid of a substation is one of the most important parts in an electrical system from the point of view of the safety of the people and equipment. Depending on the nature of the phenomena involved in the system is fault or lightning current, the behavior of grounding system is considered under steady state or transient point of view. For safety purpose of grounding grid, the ground resistance...
Flashover process on outdoor insulator is believed to be the interaction of the non-linear arc characteristic with the linear resistance of the pollution layer. Such a complex problem results in great difficulty of obtaining reliable performance of the insulator. Flashover mechanism of outdoor insulator is commonly referred to Obenaus theory in which dry band is firstly formed in the contaminated...
