SYSTEMATIC DESIGN OF ECONOP HC EARTHING MATS

Abstract

With the expansion of power systems, the increasing maximum ground fault current results in dangerous potential rise of grounding systems. The hazard can be avoided only by the control of local potentials i.e. by grounding mats. Reliability of electric system is the requirement for its good operation,and safety to human beings and equipment is the criteria for its design. Revisions in the design are being demanded keeping in view the former factor for life of the grid and later for safety. But the ever rising cost of material due to limited resources with tight import policy and long life of grid, calls for attention from economic point of view.
