This paper presents behaviour of cloud-to-ground (CG) lightning in Beaufort Sabah, Malaysia. The main contribution of this work is to investigate the behavior of cloud-to-ground (CG) lightning in Beaufort by retrieving data from Lightning Detection System (LDS). This is achieved by analyzing data from LDS for three years from year 2020 to 2022 and tabulate them into visual aids. To validate the data, a lightning detection system (LDS) which owned by Sabah Electricity Sdn Bhd (SESB) which consisting of 6 sensors in Sabah state is used to retrieve data for lightning activities in Sabah. From the analysis, it found a total number of 117,113 cloud-to-ground (CG) events in radius of 10km from Beaufort district and the pattern shows the distribution of lightning discharges (CG) for three years are increased from year 2020 to 2022. All these data are important for the purpose of lightning protection for transmission lines tower and line lightning performance in Beaufort area. © 2023 IEEE.
