On the Dispersion of Lightning Current After a Direct Flash to a Building
نویسندگان
چکیده
Simplifications often made when simulating the dispersion of lightning current can yield results that depart too much from the complex reality of a direct lightning flash to a building. The unpredictable occurrence of side-flashes increases even more the complexity. Such simulations, if taken at face value, might lead to unrealistic specifications for serviceentrance surge-protective devices (SPDs). A real-world anecdote illustrates both the complexity and a case where an SPD with only modest ratings, compared wiih some present proposak, pyovided satisfactory protection on the power-port apphances of a residence.

Transient Analysis of the Single-Conductor Overhead Lines Connected to Grid-Grounded Arrester under Direct Lightning by Means of GA
In this paper, genetic algorithm-based approach for transient analysis of single transmission line connected to arrester is proposed. In this approach, the lightning channel striking the overhead line is first represented by a current source and this source is truncated by a finite set of frequency harmonies in time domain. Norton equivalent circuit viewed across arrester is then computed by me...
متن کاملLightning mapping observation of a terrestrial gamma‐ray flash
[1] We report the observation with the North Alabama Lightning Mapping Array (LMA) related to a terrestrial gamma‐ray flash (TGF) detected by RHESSI on 26 July 2008. The LMA data explicitly show the TGF was produced during the initial development of a compact intracloud (IC) lightning flash between a negative charge region centered at about 8.5 km above sea level (−22°C temperature level) a hig...
متن کاملEstimation of Charge during a Lightning Flash Using Electric Field Measurements
1 INTRODUCTION Electric power utilities have sustained significant damage from lightning. The occurrence of line faults is one result of lightning damage. To prevent it, power utilities adopt various measures of protection from lightning. Transmission line overhead ground wires greatly contribute to a decrease in the number of line faults by preventing direct hits to the power lines. Lightning ...
متن کاملOne 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 کاملUrban Lightning: Current Research, Methods, and the Geographical Perspective
This review of urban lightning research begins with a description of cloud-toground flash data and some of the conditioning practices related to their use. Urban lightning studies from the United States and internationally are then examined to distill findings as well as to compare and contrast the modes of inquiry among the meteorologists, climatologists, engineers, and geographers who study l...
