The aim of lightning protection design is to mitigate all the factors that can impact the lightning risk. The requirements of EN62305-2 provide guidance on calculation and selection of protection levels for each specific application.
Pentair’s unique computer-aided program provides design support for a variety of design techniques and standards, including NF C 17-102. Based on individual site parameters, such as structure dimensions, terminal type and protection requirements, each Lightning Protection System Design (LPSD) is customized for the project. It provides elevation, 3-D and plan views enabling terminal location, downconductor routing and grounding system requirements to be optimized for your facility.
System Requirements: The design and installation of the terminals should be completed in compliance with the requirements of the French Standard NF C 17-102. In addition to terminal placement requirements, the standard requires a minimum of two paths to ground per terminal for non-isolated conductor systems. A downconductor cross-sectional area of ≥50 mm² is specified. The downconductors are to be secured at three points per meter with equipotential bonding made to nearby metallic items.
Each downconductor requires a test clamp and dedicated earth system of 10 ohms or less. The lightning protection ground should be connected to the main building ground and any nearby buried metallic items. The NF C 17-102 and similar ESE standards requirements for inspection and testing range from each year to every four years dependent upon location and protection level selected.Refer to your Pentair representative or the ERICO SYSTEM 1000 installation manual for additional information.
