Abstract
Dangerous is a word to describe a lightning strike effect towards human, animal and environment. A lightning strike can blows a fatality to human and causes death. Besides that, lightning strike has potential to damage property especially the transmission tower and reduces the performance of our power system transmission. Lightning cannot be diminished yet controlled by human but human can reduce the risk from getting struck to avoid the lightning by keeping a safe distance from the lightning activities area. The purpose of this project was to measure the distance of the lightning strikes. The project focused on to measure the broadband radiation generated by lightning for determination of lightning strike distance takes place in Melaka, Malaysia. The measurement conducted by using a flat-plate antenna to capture the electric field waveform of the cloud-to-ground (CG) flashes. THS4631 was used in this project as an amplifier. The electric field signal transmitted by using coaxial cables with 50 Ohm impedance. Then the electric field waveform displayed on the Teledyne LeCroy oscilloscope to be analysed. Technique of Time-of-Arrival (TOA) was used to calculate the distance of lightning strike by using delay time of arrival between the electric field antenna and magnetic field antenna. From the result, the lightning activities were detected in the range from 0.5km to 50km from the measuring station. However, lightning strikes were very unique and difficult to understand and more information and equipment needed for preparation for future research.
