ELECTRIC RAILWAY OVERHEAD FEEDING SYSTEM MODELING FOR LIGHTNING STROKE
As said previously, insulation coordination of substations is comprised of different factors, while this paper has focused on four issues, which are phase-ground BSL, phase-phase BSL, estimating BIL via a simplified method and shielding of substations against lightning strokes

to a communication tower", in Proc.
It coincides with a large, positive cloud-to-ground lightning stroke
and has the features of the signal generated by lightning's initial surge, the researchers say.
He suggests equatorial lightning strokes
might carry even higher peak currents than those measured in Florida.
Simple Distribution Transformer Model under Lightning Stroke
A numerical procedure, based on the fields approach, has been proposed to calculate the field strength caused by lightning stroke
into open area HV/MV substation.

Scientists have known for a long time TGFs were linked to strong VLF bursts, but they interpreted these signals as originating from lightning strokes
somehow associated with the gamma-ray emission.
Likewise, TGFs detectable by the GBM represent just a small fraction of intracloud lightning, with about 2,000 cloud-to-cloud lightning strokes
for every TGF.
SEDs from this superstorm (which evolved into a giant, turbulent snake completely encircling Saturn) were so frequent that Cassini's RPWS instrument sometimes could not even resolve individual lightning strokes
in the cacophony.
The topics include high-voltage switching equipment, substation integration and automation, shielding substations from direct lightning strokes
, the cyber security of substation control and diagnostic systems, and station commissioning and project closeout.
could stimulate people's brains and cause them to hallucinate bright blobs of light the same way a magnetic medical procedure does, two physicists propose in an upcoming Physics Letters A.
Aircraft soundings from the time of the event suggest little in the way of instabilit y over northern Illinois, and the lightning detection network failed to detect cloud-to-ground lightning strokes
