Abstract

This project was to develop a lightning detection system where it will be focused on measurement of magnetic field generated by lightning for determination of lightning strike direction. There are lots of detection system to determine the lightning strike such as the Lightning Positioning and Tracking System (LPATS) and Lightning Location and Protection (LLP). Magnetic direction finding is one of them. The measurement of the magnetic field produced by lightning detected using an antenna that act as a sensor. The loop antenna is developed by using PVC and coaxial cable with 50 ohm impedance is placed inside. Furthermore, the antenna is measured on the North and South component only. Output of the antenna is connected to the active integrator circuit by using AD8067 for the purpose of integrates the voltage output from the loop. PCB design of the circuit is used OrCAD software. From the circuit the measurement of the dB/dt observed the waveform on the Teledyne LeCroy HDO4024 digital storage oscilloscope (DSO). The lightning strike activity is monitored time by time. Throughout this project, the several parameter from magnetic field of the output loop antenna can determine the direction of lightning strike with some mathematic calculations and equations. The distance had been determined from the range of 0.5 km to 40 km and the lightning strike direction is defined on the East due to the cloud propagation. In conclusion, the objectives are successfully achieved and further research need to be done to increase the result accuracy of this project.
