6. Connection of HVI Conductors to an isolated ring conductor
If several parts of an installation are to be protected, it is not advisable to route the
HVI Conduc-
tor
from each air-termination system to the earth-termination system. The
HVI Conductors
from the
air-termination system can be connected to e.g. an isolated ring conductor. From this isolated ring
conductor, several down conductors can be routed to the earth-termination system. In this case, the
partitioning coefficient k
c
is reduced downstream of the isolated ring conductor and the separation
distance "s" is also reduced.
The isolated ring conductor must be installed on spacers (e.g. Part No. 106 175) and concrete bases
(Part No. 102 010). The calculated separation distance "s" must be observed.
