BS EN/IEC 62305-4 Guide to BS EN/IEC 62305
Conclusion
Lightning poses a clear threat to a structure but a
growing threat to the systems within the structure due
to the increased use and reliance of electrical and
electronic equipment. The BS EN/IEC 62305 series of
standards clearly acknowledge this. Structural
lightning protection can no longer be in isolation
from transient overvoltage or surge protection of
equipment. The use of enhanced SPDs provides a
practical cost-effective means of protection allowing
continuous operation of critical systems during
LEMP activity.
All Furse SPDs offer
enhanced SPD
performance with
industry leading low
let-through voltage
Furthermore, the capacity to protect against common
and differential mode surges permits equipment to
remain in continued operation during surge activity -
offering considerable benefit to commercial, industrial
and public service organisations alike.
All Furse SPDs offer enhanced SPD performance
with industry leading low let-through voltages
(voltage protection level, Up), as this is the best choice
to achieve cost-effective, maintenance-free repeated
protection in addition to preventing costly system
downtime. Low let-through voltage protection in all
common and differential modes means fewer units are
required to provide protection, which saves on unit
and installation costs, as well as installation time.
A Guide to BS EN 62305 Protection Against Lightning
Further to this summary on BS EN/IEC 62305,
we have available a comprehensive guide to the
BS EN 62305 standard for those interested in
learning more about the new developments
governing lightning protection design and
installation. This A4 Guide helps to explain in clear
terms the requirements of BS EN 62305. Following
the 4 sections of the standard (Part 1 - General
principles; Part 2 - Risk management; Part 3 - Physical
damage to structures and life hazard; and Part 4 -
Electrical and electronic systems within structures)
the Guide provides the information necessary to
enable the reader to identify all risks and calculate
the required level of protection in accordance with
BS EN 62305.
