Performance of bentonite and peat moss mixtures as grounding enhancement materials

Grounding system is one of the lightning protection system that meant to provide protection for a power system, equipment in it and any personnel whom might accidently in touch with it, during both normal and fault conditions. It must with a low impedance path, ensuring all fault currents to be disp...
