One case of a lightning strike leads to death: case report
Background: Lightning is one of the most mysterious phenomena of nature that also, it has caused many financial and human losses. In tropical and sub-tropical countries, death due to thunderbolt is not unusual, and even tragic events may occur at high altitudes. Lightning physics is complex and not completely clear. Usually, the clouds are heavily pregnant and high voltages and amperages, they ...
متن کاملReduction of NaTech Risk Due to Lightning by the Use of Protection Systems
Several accidents that occurred in the last decades evidenced that the impact of natural events in industrial plants may trigger accidental scenarios involving the release of relevant quantities of hazardous substances. Severe scenarios typical of the process industry, as fires, explosions, toxic releases, and water pollution were reported as the consequence of natural events in industrial area...
متن کاملIndirect Estimation of Lightning Currents from Remote Electromagnetic Field Measurements
In this lecture, the theoretical basis for the deterministic and statistical estimation of the lightning current from distant field measurements is presented. The influence of the presence of an elevated strike object on the peak of the lightning return stroke current determined from remote field measurements is also discussed.
متن کاملLightning Return Stroke Speed
The available experimental data on return stroke speed for both negative and positive lightning are reviewed. The often assumed relationship between the return-stroke speed and peak current is shown to be generally not supported by experimental data. Reasons for the return-stroke speed being lower than the speed of light are discussed. Index Terms Lightning return stroke, propagation speed, pea...
متن کاملResearch and Application of Active Lightning Protection Technology
The conventional passive lightning protection mode depending on fixed lightning rods, overhead grounded wires, arresters and SPDs couldn’t fit for the demand in practice gradually. Therefore, it is necessary to explore an available and optional way that could enhance and improve them. Based on Intelligent Control Technology and combined with lightning detection, the Active Lightning Protection ...
متن کاملBenefits of Very High Frequency Total Lightning Mapping over Very Low or Low Frequency Cloud Lightning Detection for Meteorological Applications
As a thunderstorm approaches a fixed asset (90% of the time) where people are located, VHF cloud lightning mapping provides 10s of minutes of lead time before the first cloud-to-ground strokes reach this asset. At times when a thunderstorm develops directly over the fixed asset (~10% of the time), the cloud flash detection efficiency exceeding 90% maximizes lead time during thunderstorm growth ...
