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 ...

Enhancing flashover strength along oil/pressboard interface using nanofluids
Alexandria Engineering Journal, 2020 One of the weakest paths for electrical discharge in power transformers is oil/pressboard interface. So, in this study it is aimed to enhance the flashover resistance of such interface through using the concept of nanofluids.

Testing for knowledge : maximising information obtained from fire tests by using machine learning techniques [PDF]
, 2019 A machine learning (ML) algorithm was applied to predict the onset of flashover in 1:5 scale Room Corner Test experiments with sandwich panels. Towards this end, a penalized logistic regression model was chosen to detect the relevant variables and ...

Monitoring contamination level on insulator materials under dry condition with a microwave reflectometer [PDF]
, 2016 Current techniques used for monitoring the levels of contamination on high voltage insulators, such as leakage current and infrared, are not effective in dry conditions since they require the surface of the insulator to be wetted by fog, rain or snow. If
