Measurements of electric and magnetic fields due to lightning strokes based on single-station detection

Abstract

A simple technique to determine the distance of the lightning strikes using single-station detection is described. The technique is based on ratio of the magnetics field to the electric field generated by the lightning stroke. A wire antenna was used to measure the electric field signals while magnetics loop antenna was used to measure the electromagnetics signal on the thunderstorm days. The LabVIEW software was used as a data logger to measure, analyze and calculate the lightning distance from the apparatus to the lightning stroke. The detection of the lightning activity using the developed system has been compared and validated to the Pekan Lightning Detection System (PLDS).

An Intelligent Lightning Warning System Based on Electromagnetic Field and Neural Network

“…A vertical and an orthogonal loop antenna were used to detect the induced magnetic field in order to estimate the location of a lightning strike [8,10]. The loop antenna worked based on the principle of Maxwell's Equation:…”

“…Among the different detection sensors, the EFM sensor is the most widely used owing to its advantages of high detection sensitivity and high corrosion protection ability. However, previous works focused on the development of hardware system and the existing LWS predicts occurrence of lightning strike only based on the magnitude of electric field [7][8][9][10]. From the field experience and previous published works, these fields are influenced by the temperature and humidity, lowering the prediction accuracy of a lightning strike [11][12][13].…”

Comparison Two Locations of Lightning Detection

“…To estimate accurately the distance and position of the lightning, a single DF-based lightning measuring instrument uses an orthogonal magnetic antenna loop. An orthogonal and vertical antenna loop is used for the comparison or ratio of lightning electromagnetic signals in determining the angle of lightning strikes (Ibrahim and Ghazali, 2013). The single station instrument working with a magnetic loop antenna North-South and East-West as well as coaxial cable to estimate the distance of lightning i.e the comparison between magnetic field (H) and electric field (E):…”

Lightning monitoring system for sustainable energy supply: A review

“…Fig. 12 shows the example of the coaxial cable connection in a single lightning detection station [41]. Fibre-optic cable uses thin strands of glass in its architecture.…”

“…The observational data can be displayed textually or/and graphically. The MDF method can be implemented by using a vertical and orthogonal magnetic loop/cross loop antenna and a flat plate antenna [41]. Fig.…”
