The electrical insulation between the air-termination or the down-conductor and the structural metal parts, the metal installations and the internal systems can be achieved by providing a distance d between the parts greater than the separation distance S

s-distance-

ki :depends on the selected class of LPS (see Table 10);

kc :depends on the lightning current flowing on the down conductors

km :depends on the electrical insulation material

l:is the length, in metres, along the air-termination or the down-conductor, from the point where the separation distance is to be considered, to the nearest equipotential bonding point

h :Total number of down conductors

c :Distance of a down conductor to the next down conductor

h :Spacing (or height) between ring conductors

If we don’t create S protection distance we have to use Isolated Lightning Down Conductor
