A Novel Technique to Reduce the Lightning Effect on Transmission Line

Lightning is the most deteriorated and dangerous form of over voltage and it causes hazardous effect on different power equipments, transmission lines, etc and due to it large number of physical and financial losses takes place. In this paper, I did much research on general lightning protection measure that is being taken in order to eliminate or reduce the effect of this natural disaster on different power equipments. Through survey I revealed that by applying one protective measure the effect of lightning stroke on the lines can be reduced to a greater extent. This protective measure is a small needle which when placed vertically on the overhead ground wire reduces the effect. This method can have good effect in lightning protection scheme to mitigate or nullify the over voltages induced on transmission line due to lightning effect. By theoretical analysis and with the help of some literature survey simulated results are obtained using MATLAB.
