Download complete PDF 16 MB Preface: State of the art for the installation of lightning protection systems [0.7 MB] Characteristics of lightning current [1.8 MB] Designing a lightning protection system [2.3 MB] Lightning protection system [0.7 MB] The standards define an effective lightning protection system as a set of equipment and devices to capture (never to attract) lightning and conduct it safely to ground. An improperly installed lightning protection system can cause more damage then not having any lightning protection. Protection Systems considered the national design guide for complete The purpose of a lightning protection system is to protect buildings from direct lightning strikes and possible fire or from the consequences of lightning currents (non-igniting flash). Example: Calculate Whether Lightning Protection is required or not for following Building. the technology of polycrystalline solar cells, panels and balance of components of the electrical systems are being established. Like many other engineering systems, lightning protection is not necessarily a “design preference,” but the need for a lightning protection system is determined by the requirements of NFPA 70 and NFPA 780, a lightning risk assessment, and oftentimes the facility’s insurance carrier. Standard for the Installation of Lightning . 2.1.1 Primary. electrical design of photovoltaic systems. the design and installation of LPS (Lightning Protection Systems) for structures and buildings, the protection against lightning of services entering the buildings and the protection of electrical and electronic systems. In Article " Design Calculations of Lightning Protection Systems – Part Two ", I indicated the lightning protection design process involves a number of design steps as in below Fig.1. A strike begins with a charge sep- aration in clouds. Benjamin Franklin invented the earliest lightning safety instrument, the lightning rod, in 1752. Known areas of high soil resistivity will be provided with additional ground rods or chemically enhanced ground rods, as required to achieve the specified grounding system performance. The choice of materials and the installation method should ensure a satisfactory life span of at least 30 years. Lightning protection system design calculation pdf Lightning Protection Design I. Design primary protection to prevent damage from direct lightning strokes by diverting any charges from structures through a low resistance path to earth.

Lightning protection system with single rod air terminal By protruding upwards from the building, they are likely to trig-ger the release of ascending streamers and thus be selected as impact points by lightning strokes occurring within the vicinity of the structure. (NFPA) publishes document # 780 titled . An external lightning protection system consists of one or more lightning rod ends, two or more down conductors and an earthing system. Design Standard 1) Air Terminal The air termination system used at the pinnacle is an ESEAT-SATELIT 3 60 manufactured by Duval Messien, France. This standard covers a wide range of structures that are used in commercial and industrial applications. To help the earthing system designer, the threat of lightning to a structure or building can be defined in lightning protection zones requiring protection and the type of lightning strike likely to enter the building shown in Figure 2. Lightning Protection System (LPS) BS EN/IEC 62305-1 has defined four Lightning Protection Levels (LPLs) based on probable minimum and maximum lightning currents. The lightning protection level (LPL) is generally recommended to be LPL1, which is the highest level of protection. Fundamentals of Lightning Protection Systems 3 (<3kA) lightning discharges can not be completely handled by most lightning systems in trees Cost-Effectiveness Tree lightning conductance systems are relatively expensive in labor and materials. The ESE Substantial, frequently inhabited buildings (those grounded with plumbing, electrical systems, and, if possible, lightning rods) are best.If you can’t find a substantial structure, get in a car with a metal roof and sides. ...Avoid small structures, such as stand-alone public restrooms. ...Standing under a tree is a very bad choice. ...Bring in your pets. ... Now the third revised edition of the English LIGHTNING PROTECTION GUIDE is available. In further simplification of the Conductor sizing Equation (ii); we By this means, Every new jet aircraft design undergoes more than 1,000 simulated lightning zaps to determine the protection levels and suppressor placement required for its myriad of power and signal lines. 3.2 Every installation shall be reviewed by a prior study to determine the level of protection required (See designing a lightning protection system. INTRODUCTION Lightning stroke can cause fatality structural damage, and could lead to malfunction of the electric equipment. rect lightning strikes by the use of protective conductors was first suggest-ed by Benjamin Franklin. Design Calculations of Lightning Protection Systems – Part Twenty.
