| Summary: | Abstract—The lightning strike hazards may be properly
managed by using a lightning detector system. In this paper,
a system to determine the lightning strike distance from the
measuring point was developed and tested. The time-tothunder
method was used to determine the strike distance.
The technique was implemented using two kinds of sensors,
namely, a broadband antenna to detect the electric field,
and a microphone to detect the acoustic signal produced
when lightning strike to the ground. A simple procedure to
find the strike distance (d) was explained. A broadband
parallel plate antenna was used to detect the electric field
signal. The acoustic signal was detected by a microphone.
The arrival time-delay between both signals was used to
calculate the strike distance. The LabVIEW 8.5 software
was used as a data logger to calculate the distance and to
save the data. The lightning distance data were recorded
for duration from January 2010 until March 2010 using the
developed system. The range of the lightning detection is up
to 10 km in radius. |
