Dissipate the
Lightning Energy - Point 3 of Six Point Plan
  For
the efficient performance of a lightning protection system it is
essential that a low impedance ground be provided to facilitate the
dissipation of the lightning energy into the earth mass. The ground
grid should minimize the ground voltage potential rise and thus
lessen the risk of injury to personnel or damage to equipment.
Note : Ground
Enhancement Material (GEM) or Earth Enhancing Compound is a
non-leaching soil treatment which can dramatically improve
ground grid resistance and impedance.

Connections |
 Connections are
often the weak point of electrical circuit, and especially
circuits subjected to ageing and corrosion, and to high
current. The capacity of an earthing circuit to protect the
safety of personnel depends on the quality of the connections
made.
 The CADWELD exothermic system makes it possible to produce
copper / copper, copper / aluminium, copper / steel, and
aluminium / aluminium electrical molecular bonds with no
external energy or heat source. The principle consists of
bridging together a wedding filler material and ignition agent
in a suitable graphite mould. The "weld metal" composition
depends upon the metal to be welded (copper oxide and
aluminium for a copper / copper weld). The reduction of copper
oxide by aluminium produces molten copper and aluminium oxide
slag at temperatures exceeding 2000șC. |
