How can lightning affect a grounding system?

When lightning strikes, it can generate extremely high voltage and current surges. These surges can travel through the grounding system, potentially causing damage to electrical equipment and systems connected to it. A robust grounding system is vital for safely dissipating these surges into the earth, minimizing the risk of damage or injury. The grounding system must be designed to handle these sudden surges effectively, ensuring that the electrical infrastructure remains safe and operational during and after a lightning event. Therefore, robust grounding is necessary to protect against the induced surges caused by lightning strikes.
