The function of a lightning protection system is to protect the structures from fire, mechanical, electrical & electromechanical destruction and to prevent that persons in buildings are injured or even killed. An overall lightning protection system consists of external lightning protection (lightning protection & earthing) and internal lightning protection (surge protection).
Functions of an External Lightning Protection System (ELPS)
1. Interception of direct lightning strikes via an air-termination system2. Safe discharge of lightning current to earth via down-conductor system 3. Distribution of the lightning current in the ground via an earth-termination system
Functions of an Internal Lightning & Surge Protection System (ILSPS)
Prevention of dangerous sparking in the structure by establishing an equipotential bonding or keeping a separation distance between the LPS components and other electrically conducting elements.
Lightning Equipotential Bonding (LEB)
Lightning Equipotential Bonding reduces the potential differences caused by lightning currents. This is achieved by interconnecting all isolated conducting parts of the installation by means of conductors and surge protective devices.
Evaluate the need for lightning protectionThe need for protection of a facility is established starting from the evaluation of the degree of safety required and associated risk factors. Whenever the expected strike frequency (Ne) is greater than the permissible risk (Na), protection must be installed.
(Na) The permissible risk is evaluated taking into account a series of parameters:
Impact on the immediate surroundings: The permissible risk is lower in the case of essential services which must not be interrupted, such as hospitals, fire stations, police stations, or where interruptions might cause severe environmental damage.
Building contents: The permissible risk is lower in the case of structures containing flammable or explosive substances, or where the damage might cause the irreplaceable loss of cultural heritage, for example in museums or archaeological sites.
Type of construction: The permissible risk varies depending on the structural or roof material.
Building occupancy: The permissible risk is lower in the case of buildings open to the public, or healthcare, retail sales or educational occupancies. The permissible risk is also lower if the structure is difficult to evacuate, or where there is a risk of panic, as for example in theatres, schools, shopping centres and sports venues. (Ne) The expected lightning strike frequency is calculated bearing in mind the following parameters:
Density of ground strikes (Ng): The number and intensity of storms depend on the topography of each region. This data is shown on the isokeraunic map.
Location of the building in relation to the surroundings and their height: The risk of a strike is greater in the case of a structure which is isolated, surrounded by lower buildings or on a hill or promontory.
Equivalent capture area of the structure to be protected: The greater the surface area exposed to lightning, the greater the risk of a strike.
The calculation of the need for protection is quite complex and depends on the applicable regulatory framework.
