Applications
Example 2: Tests on multi-grounded (inter-connected) systems:
Ground conductors are for example bonded to grids or concrete-footing grounds and
other conducting elements such as lightning protection systems or frameworks.
In this case the resistances of individual ground paths are not of significance.
It must be tested if the resistance of the bonding is sufficiently low and reliable.
