IEEE Transactions on Electron Devices, 1990 Empirical information about surface flashover of silicon in a vacuum ambient which shows that in breakdown the current is carried primarily inside the semiconductor is presented. This observation shows that the physical processes responsible for flashover of silicon are fundamentally different from those assumed in the standard model for flashover of ...

Influence of single and multiple dry bands on critical flashover voltage of silicone rubber outdoor insulators: simulation and experimental study [PDF]
, 2018 Dry band formation on the surface of outdoor insulators is one of the main reasons leading to flashover and power outages. In this paper, a dynamic arc model is proposed for single and multiple dry bands configuration to predict the critical flashover ...

A Scoping Review and Bibliometric Analysis on Smart Firefighting in Buildings and Infrastructures
Fire and Materials, EarlyView.ABSTRACT Smart Firefighting is a concept that has emerged within the fire engineering and fire science disciplines in recent years. It can enable informed decision making and improved fire safety. However, its scope, definition, outcomes, and value to emergency management remain unclear. To investigate this, a scoping review and a bibliometric analysis
