What happens to ground resistance in systems that require sensitive electronic equipment?

In systems that involve sensitive electronic equipment, maintaining low ground resistance is crucial to ensure proper operation and safety. Ground resistance should ideally be minimized to 1 ohm or less to provide an effective path for fault currents. This low resistance helps prevent damage to the equipment due to voltage spikes and electromagnetic interference, which can otherwise affect performance and reliability.

Sensitive electronic equipment often relies on stable and low noise environments. High ground resistance can lead to voltage differences that might impact the functioning of these devices. Moreover, in the event of a fault, such as a short circuit, low ground resistance allows for the quick dissipation of harmful currents, thereby enhancing safety and preventing equipment damage.
