PROTECTION RADIUS OF SMART ESE-98 LEADER
DIMENSION OF SMART ESE-98
When lightning strikes, an electrical field is always created at ground level and this increases in
intensity as the «downward leader» approaches. Once this reaches a certain level – between 50
and 100 kV/m – the Corona effect, which develops naturally at the top of any high structure, allows
discharges – known as upward leaders – to rise toward the cloud (see previous section on the
The position of the ionised path which will allow the lightning current to pass is determined by where
the upward leader comes into contact with the first downward leader from the cloud.
The sooner the rising discharge (upward leader) leaves the lightning conductor to move toward the
cloud, the sooner it will move closer to the downward leader and the greater the chances of the
two making contact before other rising discharges from nearby high points. It can be seen, then,
that it is the start point of the first upward leader which determines the point of impact of the lightning
on the ground. An early streamer emission lightning conductor is designed to provide optimal
conditions for the formation of this rising discharge.
For this the following conditions are necessary :
1, The presence of primary electrons at the top of the terminal: these electrons, given off in the form
of plasma, encourage the start-up of the rising discharge.
2, Onised plasma being formed at the right moment when lightning is about to strike, in other words,
in phase with the rising electric field at ground level.
