WebGrounding grids rely on conductive mesh or sheets to create several paths for electrical energy to find its way to ground. Grounding grids limit potential differences between pieces of equipment and stop ground loops. They also reduce mains hum and minimize touch potential. Grounding grids are critical in static discharge and lightning protection. WebIEEE Standard 80-1976 is primarily concerned with ground gradient of substation installations. Large industrial petrochemical plants demand bulk power supply from substations and, coupled with cogeneration plants, make the design of the grounding system rather complex and costly due to high ground fault currents. The basic design criteria in …
