Characteristics of Triggered Lightning Observed in Brazil
Several parameters of return-stroke current waveforms of triggered lightning are discussed and compared to results obtained in other places. The parameters presented in this paper, obtained for the first time in Brazil, are crucial in the lightning protection research. All these measurements were done with a sample rate of 100 ns, enabling us to study rise and decay times of the waveforms. Imag...
متن کاملLightning Protection of Overhead Power Distribution Lines
Distribution lines are often located in areas with high ground flash densities, being therefore subject to lightning-caused power interruptions. This paper presents an overview of the various types of lightning overvoltages that can arise on overhead power distribution networks, as well as typical voltage waveforms. The effectivenesses of the most important methods for mitigating such overvolta...

15 صفحه اولAn evaluation of the performance characteristics of the U.S. National Lightning Detection Network in Florida using rocket-triggered lightning
[1] The performance characteristics of the U.S. National Lightning Detection Network (NLDN) were evaluated using rocket-triggered lightning data, acquired in the summers of 2001–2003 at the International Center for Lightning Research and Testing (ICLRT), at Camp Blanding, Florida. During the 3-year period, 37 flashes, containing a total of 159 (158 negative and 1 positive) strokes, were trigger...
متن کاملInsights into the ground attachment process of natural lightning gained from an unusual triggered-lightning stroke
[1] We present measured electric and magnetic field and current derivatives from an unusual triggered-lightning stroke that was initiated by a dart-stepped leader and that involved an upward connecting leader. The initial rising portion of the current (integrated dI/dt) waveform is composed of a ‘‘slow front’’ rising to 20 kA in 2.2 ms, followed by a ‘‘fast transition’’ from 20 to 27 kA in 0.2 ...
