Breakdown at Multiple Protrusions in SF6 and CO2

Measuring Breakdown Probabilities of Sf6 Insulated, Low Inhomogeneous Electrodes

It is well known that increased surface roughness of SF6 insulated electrode arrangements is significantly lowering the breakdown voltage [1], [2]. This effect becomes stronger with rising pressure and homogeneity of the electrodes. Since each breakdown changes the surface condition of the electrodes, it becomes very ambitious to measure breakdown probabilities in a statistical meaningful way. ...

Location-Allocation and Scheduling of Inbound and Outbound Trucks in Multiple Cross-Dockings Considering Breakdown Trucks

This paper studies multiple cross-dockings where the loads are transferred from origins (suppliers) to destinations (customers) through cross-docking facilities. Products are no longer stored in intermediate depots and incoming shipments are consolidated based on customer demands and immediately delivered to them to their destinations. In this paper, each cross-docking has a covering radius tha...

Breakdown Characteristics of SF6/CF4 Mixtures in Test Chamber and 25.8kV GIS

SF 6 gas has excellent dielectric strength, but it causes global warming about 23900 times more than CO 2 gas which is the main cause of global warming. This shows necessity of the environment friendly dielectric gas which can replace SF 6 gas. We made the test chamber which simulated inner of the gas insulation switchgear (GIS) and 25.8kV GIS of 3 phase unity bundle operation tank type. The br...
