Lightning Protection System (LPS) BS EN/IEC has defined four Lightning Protection Levels (LPLs) based on probable minimum and maximum lightning currents Furse, Wilford Road, Nottingham, NGEB Tel: +(0)1• Email: enquiry@: fBS EN/IEC Guide to BS EN/IEC Lightning Protection Levels (LPL) LPL Four protection levels have been determined based on parameters obtained from previously published technical papers It is assumed that the maximum current due to a lightning strike would be kA and that BS EN Risk managementPerception of riskRisk management procedureUK and world mapsBS EN Physical damage to structures and life hazardLightning Protection System (LPS)BS EN Electrical and electronic systems within structuresScopeSurge Protection Measures (SPM) Measures System (LPMS) in IEC/BS EN Figurehighlights the LPZ concept as applied to the structure and to SPM. The concept is expanded upon in IEC/BS EN and IEC/BS EN Selection of the most suitable SPM is made using the risk assessment in accordance with IEC/BS EN Arandela de estanqueidad integrada: ajuste BS:EN prescribes how to assess the risk of lightning in respect of loss of life, loss of vital service, economic loss, loss of heritage and physical damage. FigureSources of damage arising from a lightning srike The main body of this part of the standard gives guidance on the design of an external Lightning Protection System (LPS), internal LPS and maintenance and inspection programmes. This document discusses lightning protection systems according to BS EN It describes the four lightning protection levels which determine the class of lightning protection system required based on risk assessment BS:EN introduces key concepts that we used in designing a Lightning Protection System.
