BS EN is the latest reference document for protection against lightning. Lightning Protection – Out with the old, in with the new StrikeRisk for lightning calculations Overvoltage – When lightning strikes.

Part 3 Physical damage to structures and life hazards The third part of the new standard relates directly to the main body of BSbut there are significant differences between the two. Call to action for investment in training.
Omega Brochures Open product brochure Height safety brochure. However, for an existing structure, retrofitting a set of co-ordinated SPDs is likely to be the easiest and most cost-effective solution. A lightning protection system commissioned or installed on a structure prior to this date should be maintained to BS Learn more about the cookies we use and how to change your settings.

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. Part 1 General principles This is an introduction to the other parts of the standard.
It requires the bonding of all metallic services to the main equipotential bonding bar. SPDs also provide additional protection over bonding and shielding measures through protection in both common and differential modes. In BS a system was used where each down conductor was attached to an earth electrode. Standard Number BS 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.
The new standard consists of four parts: 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. BS EN came into force on 1 September The faster, easier way to work with standards.
However, BS EN details the use of air rods or finials, catenary or suspended conductors or a meshed conductor network, in any combination. 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.
Lightning protection – Mastering the maze of BS EN
If the actual risk R is lower than the tolerable risk RTthen no protection measures are needed. The first stage of the risk assessment is to identify the types of loss that a structure and its contents can incur. Switches support high performance.

This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. This standard includes the following cross references: Protcetion EN contains a series of National Annexes, from which individual countries, like the UK, have used their own interpretation and perception of risk to compile parameters for certain elements of the risk assessment.
At the moment, it runs be with BSbut ultimately BS will be withdrawn and BS EN will be the only recognised standard by the end of August Once the applicable types of loss have been identified, a tolerable risk RT for each can be looked up in a table contained in the National Annexes.

This British Standard outlines the general technical aspects of lightning, illustrating its principal electrical, thermal and mechanical effects. BS EN is applicable to risk assessment for a structure due to lightning flashes. Lgihtning British Standard provides guidance on the design of systems for the protection of structures against lightning and on the selection of materials.
SPDs are required under BS EN ; they are part of the internal LPS and are installed firstly to prevent dangerous lightning currents from entering a building via its services, and secondly to reduce the risk of damage to electrical and electronic equipment and critical systems from transient over-voltages.
