Analysis of a back flashover across insulator strings on a 115 kV transmission line tower by PSCAD

open access: yesKKU Engineering Journal, 2015
Lightning striking on a transmission tower induces high ground potential rise and high voltage at tower arms in which potential is normally at ground level, and subsequently causes overvoltage across an insulator string.

Evaluation of Kapton pyrolysis, arc tracking, and flashover on SiO(x)-coated polyimide insulated samples of flat flexible current carriers for Space Station Freedom [PDF]

open access: yes
Kapton polyimide wiring insulation was found to be vulnerable to pyrolization, arc tracking, and flashover when momentary short-circuit arcs have occurred on aircraft power systems.

Effects of carbon/graphite fiber contamination on high voltage electrical insulation [PDF]

open access: yes
The contamination mechanics and resulting failure modes of high voltage electrical insulation due to carbon/graphite fibers were examined. The high voltage insulation vulnerability to carbon/graphite fiber induced failure was evaluated using a ...

Sessile water droplets on insulating surfaces subject to high AC stress effect of contact angle [PDF]

open access: yes, 2002
Surface pollution of outdoor high-voltage insulators is an important cause of flashover. We have undertaken an experimental study of electrical breakdown at the edges of a sessile water droplet on a planar, polymeric, insulating surface when subject to ...

Characteristics of EMI generated by negative metal-positive dielectric voltage stresses due to spacecraft charging [PDF]

open access: yes, 1985
Charging of spacecraft surfaces by the environmental plasma can result in differential potentials between metallic structure and adjacent dielectric surfaces in which the relative polarity of the voltage stress is either negative dielectric/positive ...

Influence of fluorination time on surface flashover of epoxy in insulating gas [PDF]

open access: yes, 2015
The accumulation of charges on polymeric insulation under high voltage DC stress is a major concern in the transmission system as its formation distorts the local electric field and has an adverse impact on the electrical performance.

An Underappreciated Radiation Hazard from High Voltage Electrodes in Vacuum

open access: yes, 2016
The use of high voltage (HV) electrodes in vacuum is commonplace in physics laboratories. In such systems, it has long been known that electron emission from an HV cathode can lead to bremsstrahlung X-rays; indeed, this is the basic principle behind the ...
