Conventional LPS

A conventional LPS (lightning protection system) refers to a traditional or standard approach to protecting a building or structure from lightning strikes. It typically consists of a set of components designed to intercept, conduct, and safely dissipate the electrical current of a lightning strike.

A lightning protection system is a set of components and equipment that are installed on a building or structure to protect it from damage caused by lightning strikes. The primary purpose of a lightning protection system is to provide a low-resistance path for the lightning current to safely pass through and into the ground, thereby reducing the likelihood of damage to the structure and its occupants.

The main components of a conventional LPS – lightning protection system include:

1. Air Terminals (Lightning Rods): These are metal rods or rods with pointed tips that are strategically placed on the highest points of the structure. They provide a preferred path for the lightning to strike and help to prevent lightning from striking other vulnerable parts of the building.
2. Downconductors: These are conductive cables or rods that connect the air terminals to the grounding system. They serve to conduct the lightning current from the air terminals to the ground.
3. Grounding System: This is a network of conductive materials, such as copper or aluminum rods, buried in the ground. The grounding system provides a low-resistance path for the lightning current to flow into the earth, dispersing it safely.
4. Bonding and Surge Protection: In addition to the main components, a conventional lightning protection system may also include bonding conductors to interconnect metal objects on the structure, such as pipes or structural components, to ensure equal potential during a lightning strike. Surge protection devices may also be installed to protect sensitive electrical and electronic equipment from voltage surges caused by lightning.

Overall, a conventional lightning protection system aims to minimize the risk of structural damage, fire, and injury by providing a path of least resistance for lightning to follow, directing it safely into the ground.
