Grounding Practices in Power Distribution Systems
Equipment Protection: Grounding protects substation equipment from potential damage from lightning strikes, fault currents, and transient overvoltages. The
Distribution System Grounding
It is recommended to ground the neutral at various strategic locations in distribution substations, overhead lines and underground cables, distribution transformers, and all loads.
Practical steps in the design of a substation grounding
Grounding at power substations is extremely important. The grounding system provides the ground connection for the grounded neutral for
