The parallel continuous type of counterpoise wire is the best ground system currently, it is reduce the ground resistance less than 25 ?? in high resistivity of soil arriving 4450 ??m with 400 m length. The created ground system types of proposed chem-counterpoise can be used in both homogenous and inhomogeneous soil that have soil resistivity arriving 10000 ??m. The proposed chem-counterpoise devices...
Lightning has been a major concern to the power system researchers because it can cause damage to the connected electrical equipment and transmission failure. One study carried out is that where the level of voltage at a substation is observed following a backflashover analysis on a transmission line. Sample of worst case transmission line was taken from Tenaga National Berhad, which is 132 kV Kuala...
In this paper, I did much research on the base of the general lightning protection measure. By referring to lots of literature, the author proposed one new lightning protection measure-add horizontal side needle on side of overhead ground wire. This method can has good effect in lightning protection. By theoretical analysis and calculation, we designed a scale model of this new measure. Then we did...
