The need for BS EN 62305-4:2006 has arisen due to the increasing cost of failures of electrical and electronic systems, caused by electromagnetic effects of lightning.
Permanent failure of electrical and electronic systems can be caused by the lightning electromagnetic impulse (LEMP) via:
a) conducted and induced surges transmitted to apparatus via connecting wiring
b) the effects of radiated electromagnetic fields directly into apparatus itself.
BS EN 62305-4:2006 provides information on protection measures to reduce the risk of permanent failures of electrical and electronic systems within structures.
BS EN 62305-4:2006 provides information for the design, installation, inspection, maintenance and testing of a LEMP protection measures system (LPMS) for electrical and electronic systems within a structure, able to reduce the risk of permanent failures due to lightning electromagnetic impulse. It also provides guidelines for cooperation between the designer of the electrical and electronic system, and the designer of the protection measures, in an attempt to achieve optimum protection effectiveness.
BS EN 52305-4:2006 contains:
- Normative references
- Terms and definitions
- Design and installation of a LEMP protection measures system (LPMS)
- Earthing and bonding
- Magnetic shielding and line routing
- Coordinated SPD protection
- Management of an LPMS
