Abstract
This study, presents a new trend methodology for the cost minimization of an earthing grid system. To optimally, design an earthing grid system researchers apply a geometric programming approach. In this approach, the cost minimization variable is positive and the constraints are expressed in a posynomial form. In forming the cost minimization variable researcher took into consideration the cost of grid conductor, excavation cost and joint welding cost. The simulated result shows the geometric programming approach was able to predict the total length of conductor, the grid configuration, the depth of burial and diameter of conductor cross section required to design an earthing grid system that meets the optimal safety criterion, as well as cost of installation.
