Ring grounds should be installed beyond the building's drip line to prevent corrosion of the ring's metal. Ring grounds are very commonly used around communications equipment such as cell phone towers, police radio towers, and other types of radio towers and equipment buildings. They are also often used to protect computer data centers.
A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike.

The danger of a lightning strike depends on several factors, including where a person is when being struck, the kind of object someone is holding or even the amount of water on the person's skin.
The large area is required to dissipate the high current of a lightning strike without damaging the system conductors by excess heat. Since lightning strikes are pulses of energy with very high frequency components, grounding systems for lightning protection tend to use short straight runs of conductors to reduce the self-inductance and skin ...
We walked into the house about 8:30 at night. It was almost dark – not completely – which perhaps was why we didn't notice that the lights weren't operating at full strength. The floor ...
Faraday cages are also used to protect people and equipment against electric currents such as lightning strikes and electrostatic discharges, because the cage conducts electrical current around the outside of the enclosed space and none passes through the interior.
Worried about lightning? Here’s how to plan your Myrtle beach vacation around stormy weather.
