Appropriate SPDs should be fitted wherever services cross from one LPZ to another Conclusion So, this brief overview of the new BS EN lightning protection standard clearly demonstrates how it is more complex and exacting than its predecessor.

Part 4 Electrical and electronic systems within structures This part contains one of the most critical differences between the two standards. The faster, easier way to work with standards. BS EN provides the general principles to be followed in the protection of structures against lightning, including their lighgning and contents as well as people.

BS EN lightning protection systems comprise external structural and internal surge protection etc. If R is greater than RT, then protection measures, as determined from the tables given in the standard, are required.

The protection of telecommunication lines and equipment against lightning dischargesUL BS EN provides the requirements for protection of a structure against physical damage by means of a lightning protection system LPSand for protection against injury to living beings due to touch and step voltages in the vicinity of an LPS. You may experience issues viewing this site in Internet Explorer 9, 10 or protedtion For new builds, bonding and screening measures can be integrally designed to form part of the complete lightning protection measures system LPMS.


BS EN came into force on 1 September Lightning and surge protection.

A lightning protection system commissioned or installed on a structure prior to this date should be maintained to BS This British Standard outlines the general technical aspects of lightning, illustrating its principal electrical, thermal and mechanical effects. Abstract This British Standard provides guidance on the design of systems for the protection of structures against lightning and on the selection of materials.

This simply means a series of SPDs whose locations and LEMP handling attributes are co-ordinated in such a way as to protect the equipment in their environment by reducing the LEMP effects to a safe level.

British Standards relating to Lightning Protection

The guidance provided is of a general nature and its application to specific lightning protection installations has to take into account the particular conditions pertaining to those installations.

Surge protection devices SPDs were not required previously to comply with older standards. From that risk assessment, a structure may need both a structural LPS and a fully co-ordinated set of surge protection devices SPDs or just overvoltage protection alone.

The new standard also includes three methods for determining the position of the air termination system: Contact Publications Site Map. General principles Part 2: The four parts are as follows: Omega Brochures Open product brochure Height safety brochure. Resources and Waste Strategy release.

Your basket is empty. The first stage of the risk assessment is to identify the types of loss that a structure and its contents can incur.


LPZ 1 sees limited induced current and damped magnetic field whilst LPZ 2 has a further reduction of induced current and further damped magnetic field. Electrical and electronic systems within buildings.

Lightning protection – Mastering the maze of BS EN

It requires the bonding of all metallic services to the main equipotential bonding bar. In BSthe protection of electronic equipment is only included in an informative annex.

So there may be a heavy duty lightning current Type I SPD at the service entrance to handle the majority of the surge energy, plus downstream overvoltage SPDs to protect terminal equipment.

BS EN bw applicable to risk assessment for a structure due to lightning flashes. Customers who bought this product also bought BS Lightning Protection – Out with the old, in with the new StrikeRisk for lightning calculations Overvoltage – When lightning strikes. BS recommends the inspection of any LPS annually.

This ensures equipment is not only protected from damage but also remains operational during lightning activity. You may find similar items within these categories by potection from the choices below:. The actual risk R is then arrived at through a series of calculations, using formulae in the standard and including various weighting factors.

However, BS EN details the use of air rods or finials, catenary or suspended conductors or a meshed conductor network, in any combination. Click to learn more. When applying bonding, shielding and SPDs, technical excellence must be balanced with economic necessity.
