BS EN will take some time for people to fully interpret and comprehend, but by using the resources available, the issues they may initially encounter certainly can be mastered.

In BSthe protection of electronic equipment is only included in an informative annex. However, the key principles are well established and pretty familiar to all.


Electrical and electronic systems within structures Status: For new builds, bonding and screening measures can be bd designed to form 6230-54 of the complete lightning protection measures system LPMS. You may find similar items within these categories by selecting from the choices below:. BS recommends the inspection of any LPS annually. 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.

Part 4 Electrical and electronic systems within structures This part contains one of the most critical differences between the two standards. Protection levels within a zone be be co-ordinated with the immunity characteristics of the equipment to be protected, ie, the more sensitive the equipment, the more protected the zone required.

Call to action for investment in training. Take the smart route to manage medical device compliance. Lightning Protection – Out with the old, in with the new StrikeRisk for lightning calculations Overvoltage – When lightning strikes.

Lightning protection – Mastering the maze of BS EN

Structural lightning protection cannot now be considered in isolation from transient overvoltage or surge protection. BS EN goes further, categorising inspection into visual inspection, complete inspection and critical systems complete inspection, whose frequency depends on the LPL in force.

Expanding on an article in the May issue of Electrical Review John Sherlock of Furse pictured rightoffers an overview of the new standard and the consolation that, complex as the new standard may be, its key concepts are not alien, and, with relevant technical advice and support, it can be mastered. However, BS EN details the use of air rods or finials, catenary or suspended conductors or a meshed conductor network, in any combination.

Part 3 Physical damage to structures bz life hazards The third part of the new standard relates directly to the main body of BSbut there are significant differences between the two. 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.

Resources and Waste Strategy release. SPDs also provide additional protection over bonding and shielding measures through b in both common and differential modes. The BS British Standard on lightning protection has existed for decades. It requires the bonding of all metallic services to the main equipotential bonding bar. This ensures equipment is not only protected from damage but also remains operational during lightning activity.
