  • Grounding is essential to build effective lightning protection design for electric power equipment. The main role of grounding is to disperse abnormal current such as that from lightning into the soil via a grounding electrode. When the lightning current flows into the grounding electrode, the electrical potential of the electrode rises, and overvoltage arises between the equipment connected to the grounding electrode and nearby equipment. The overvoltage causes equipment to breakdown or… CONTINUE READING
