  How much does the layout of earthing conductors affect the overall earth resistance?

  Basic definition and function of grounding resistanceGrounding resistance is an important parameter to measure whether the connection between electrical equipment and the earth is reliable. The lower its value, the better the grounding effect. The grounding system introduces currents such as lightning and electrical faults into the earth through the earthing conductor, thereby playing a protective role. Whether in power systems, building facilities or industrial control equipment, grounding resi...

  What role do ground rods play in a lightning protection system?

  In the lightning protection system, the ground rod is a vital component. It is responsible for guiding the lightning current into the ground quickly and safely, thereby effectively reducing the risk of lightning damage to buildings, electrical equipment and personnel. The ground rod is usually buried deep underground. Through its good conductivity, the lightning current can be quickly dispersed to the earth, avoiding the high voltage difference caused by the lightning current stagnation near the...
