This opening part of the BS EN 62305 suite of

standards introduces the reader to the other

parts of the standard.

It defines by its five annexes the lightning

current parameters that are used to design and

then select the appropriate protection measures

detailed in the other parts.

Damage due to lightning

There is an initial focus on the damage that can be

caused by lightning. This is sub-divided into:

● Damage to a structure (including all incoming

electrical overhead and buried lines connected to

the structure)

● Damage to a service (service in this instance being

part of telecommunication, data, power, water,

gas and fuel distribution networks).

NOTE: BS EN 62305-5 (part 5), which relates to

this latter type of damage, will ultimately be

deleted from the standard. See the explanation

on page 10.

Damage to a structure is further subdivided into

sources of damage and types of damage.
