Lightning is a natural phenomenon that can cause significant damage to transmission lines. The overvoltage caused by lightning strikes can lead to insulation failure, which can result in equipment damage, service interruption, and in some cases, fatalities. In order to protect the transmission lines from lightning-induced overvoltage, various techniques and protective devices have been developed. The use of light storm overvoltage (LSOV) technology is one of the most effective methods for protecting transmission lines from lightning strikes. This review paper aims to study and evaluate the LSOV technology for the protection of transmission lines. The review paper provides an overview of the LSOV technology and its principles of operation. The paper analyzes the various types of LSOV technology, such as shield wires, surge arresters, and surge protectors, and their advantages and limitations. The study evaluates the performance of LSOV technology in protecting transmission lines against lightning strikes based on various parameters, such as voltage, current, frequency, and duration of the overvoltage. Furthermore, the review paper discusses the different testing methods and standards used to evaluate the effectiveness of LSOV technology. The paper also highlights the challenges and limitations of the LSOV technology, such as installation costs, maintenance, and reliability..
