CN Tower Lightning Return-Stroke Current Simulation
Different functions have been used to model the lightning return-stroke current with the aid of direct current measurements at tall structures. In this paper, a comparison between the Pulse function and Heilder function is carried out to find out the suitability of each of these functions for simulating the lightning return-stroke current, measured at the CN Tower. An automated system for deter...
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 کاملComparative study of adaptive techniques for denoising CN Tower lightning current derivative signals
a r t i c l e i n f o a b s t r a c t The lightning current derivative data recorded at the CN Tower during the past 18 years contain different kinds of noise and needs to be denoised for accurately determining the lightning current waveform parameters. It is usually a challenging task to denoise transient signals having large bandwidth without altering their waveshapes or shrinking their ampli...
متن کاملPerformance Analysis of the North American Lightning Detection Network Using Cn Tower Lightning Data
The North American Lightning Detection Network (NALDN) is a commercial lightning detection network composed of the U.S. National Lightning Detection Network (NLDN) and the Canadian Lightning Detection Network (CLDN). The NALDN was developed to provide lightning information by accurately detecting and locating most cloud-to-ground (CG) lightning strokes and a small fraction of discharges produce...
متن کاملTall-Structure Lightning Return-Stroke Modelling
A lightning return-stroke model, based on the lightning return-stroke current derivative measured at the Toronto CN Tower is presented in this paper. A 3-section transmission line representation of the CN Tower along with the derivative of the modified Heidler function is used to simulate the measured current derivative signal. Reflections from major structural discontinuities of the CN Tower a...
