Description
In accordance with NF C15-100, the quality of an earth connection
(resistance as low as possible) is primarily a function of
two factors:
- The embodiment,
- The nature of the soil (resistivity).
Resistivity can be measured by the WENNER method with 4 stakes.
According to the NF C15-100 I have reported in the application the average values of the resistivity to make a calculation
approximate earth connections.
To be more precise you can
measure this resistivity and report
your measurement in "Other value".
In this application are represented
all the embodiments of current use. You will find :
- The straight bare conductor
- The earth stake
- The vertical plate
- The horizontal grid
- The bottom digging loop
The best solution of the mode of
realization and the most widespread is
the full digging loop.
For each embodiment, you can also go to a merchant site in order to have visibility on the type of products to be implemented and the price. I also put you measuring devices allowing to measure the resistivity and the resistance of the ground.
