Impact and Mitigation of Icing on Insulator Flashover by Masoud Farzaneh Ice and snow accretion on power equipment such as conductors, ground wires and insulators are a concern to engineers in many regions The disruptive effects result mainly from excessive ice and snow accumulation, combined...
A thermal image video was used to record the suppression procedure inside room. Test results show that the water mist system is efficient in suppressing the flashover of GRP fire and cooling the room within short time.doi:10.2298/TSCI090508038XXu Qiang...

By measuring the variation of the current as function of time and observing the insulator surface with a video camera allow to decompose the components of a flashover cycle. First, the current slowly increases. In the steady state the I(V) curve is of Space Charge Limited Current type. Then...
Finally, a video camera system is used to support this investigation by laboratory observations of the full process of flashover mechanism. The obtained results show that there is a width limit approximately equal to 8 cm beyond which several arcs, parallel, consecutive and independent can develop....
Optical data collected by a video camera along with the PMT light emission data are analyzed and the analysis results of the optical emission characteristics of surface flashover are presented. The samples used in the experiments were produced by using either epoxy resin of known properties or by ...
In this paper, the phenomena of surface flashover, including the infrared video, flashover spectrum and the voltage waveforms are presented to research...doi:10.1002/mop.31175Weili JiWei ShiCheng MaJuncheng CaoMicrowave and Optical Technology Letters...
To make the effect of resonant vibration on flashover via the water droplet clear, the time variation of the shape of a 30 渭l droplet placed between the parallel electrodes was observed with a high-speed video camera. The flashover voltage via the droplet at the resonant frequency of 19 Hz...
According to video recording of the flashover process, how the factors (distance between adjacent strings and equivalent salt deposit density (ESDD), etc.) influenced the development of the electric arc was studied. It was found that: the relationship between flashover voltage of insulator (string...
