Meaning and Definition
A device installed on electrical systems or tall structures to protect them from lightning strikes by providing a safe path for the electrical discharge to reach the ground.
More broadly, any system or measure designed to intercept and neutralize a sudden, powerful threat before it causes damage. It can be used metaphorically for a person or policy that prevents crises.
Dialectal Variation
British vs American Usage
Differences
Spelling is consistent. Usage is identical in technical contexts. The device may be referred to more informally in AmE as a 'lightning rod' (though a rod is technically a component of an arrester system).
Connotations
Identical technical connotations. Potential for the same metaphorical extension in both varieties.
Frequency
Equally low frequency in both, confined to specific technical fields like electrical engineering, construction, and telecommunications.

FAQ
Frequently Asked Questions
No, they are related but distinct. A lightning rod (or air terminal) is the point that intercepts the strike. A lightning arrester is a device, often connected to the rod's down-conductor, that controls the voltage surge and prevents it from entering a wiring system.
On power transmission lines, telephone exchanges, electrical substations, and at the service entrance of large buildings to protect internal wiring and equipment.
Yes, though it's not common. It can describe a person or mechanism that absorbs or deflects a sudden, disruptive force, such as in a tense social or political situation.
A failure can lead to catastrophic damage. The high-voltage surge from the lightning strike would travel unprotected into the electrical system, causing fires, destroying sensitive electronics, and potentially leading to electrocution hazards.
A device installed on electrical systems or tall structures to protect them from lightning strikes by providing a safe path for the electrical discharge to reach the ground.
