Arc Routing with Time-Dependent Travel Times and Paths [PDF]
Vehicle routing algorithms usually reformulate the road network into a complete graph in which each arc represents the shortest path between two locations. Studies on time-dependent routing followed this model and therefore defined the speed functions on the complete graph.

Mechanism of saline deposition and surface flashover on high-voltage insulators near shoreline:mathematical models and experimental validations [PDF]
This paper deals with sea salt transportation and deposition mechanisms and discusses the serious issue of degradation of outdoor insulators resulting from various environmental stresses and severe saline contaminant accumulation near the shoreline.

Numerical investigation of the double-arcing phenomenon in a cutting arc torch [PDF]
A numerical investigation of the double-arcing phenomenon in a cutting arc torch is reported. The dynamics of the double-arcing were simulated by using a two-dimensional model of the gas breakdown development in the space-charge layer contiguous to the ...

Time dependent nature of the Neptune’s arc configuration [PDF]
By distinguishing the main arc Fraternite from the minor arcs Egalite (2,1), Liberte, Courage, the restricted three-body system is extended to a non-conservative restricted four-body system with the central body Neptune S, the primary body Galatea X, a minor body Fraternite F, and a test body s.

Investigations on the safe stroke of mechanical HVDC vacuum circuit breaker
Here, a DC vacuum arc interruption test based on the hybrid high-speed actuator and the method of commutation is carried out in the synthetic loop system. The safe stroke is one of the basic breaking parameters.

Gas flow–switching arc interaction in HV synchronous gas blast interrupters [PDF]
The paper is devoted to the solution of short-circuit switching problem in distribution networks by application of synchronous HV gas-blast circuit breakers (SCB). The reduction of the arcing energy by reducing the arcing time can extend the SCB expected

Effect of Magnetic Field on Different Opening Processes of Multi-Break Vacuum Gaps
Vacuum gap saturation of single break can be solved by multiple breaks in series. In different breaking processes, the unbalanced energy and charges injected into the breaks lead to unbalanced voltage distribution.
