Review of Insulation Defect Detection Methods for a Gas-Insulated Switchgear
EnergiesGas-insulated switchgear (GIS) is a critical component of modern power systems. During operation, internal defects increase the probability of partial discharge and flashover within the insulation system, thereby constituting a major cause of equipment ...

Defect mediated manipulation of nanoclusters on an insulator [PDF]
Scientific Reports, 2013 With modern scanning probe microscopes, it is possible to manipulate surface structures even at the atomic level. However, manipulation of nanoscale objects such as clusters is often more relevant and also more challenging due to the complicated interactions between the surface, cluster and apparatus.

Point defects in tight binding models for insulators [PDF]
Mathematical Models and Methods in Applied Sciences, 2020 We consider atomistic geometry relaxation in the context of linear tight binding models for point defects. A limiting model as Fermi-temperature is sent to zero is formulated, and an exponential rate of convergence for the nuclei configuration is established.
