AB  - 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.
