The principle of operation of the fattened device of does not use any fragile
component (that is to say, without risks of failures).
The precision of ionization is only, we spoke of microseconds.
The materials utilizadospara its manufacture: it receives, stainless steel, etc. have
been chosen by his excellent corrosion resistance.
By his autonomy and reliability they allow to be installed in places difficult like for
example the bell towers.
Realized
tests
As of 1995 July, the effectiveness of the lightning rods with devices of fattened is determined according to the results obtained in the laboratory according to the tests of evaluation of norm NF 17-102.
The
realized tests, have given the following results:
| Fattened advance of measured experimentally in wave of 300 µs: |
64.3 µs |
| Fattened advance of according to reference to the standard wave: |
129 µs |
| Used fattened advance of average for the calculation of the protection radii: |
86 µs |
