Table 6: Potential compensation between two connections
A potential compensation line must have the following features:
X Low impedance. The lower the impedance, the more effective is
the potential compensation. In the case of compensation lines
that are laid on both sides, the compensation line impedance
must be considerably smaller than that of the shielding
connection (max. 10% of shielding connection impedance).
X Sufficient dimensioning of the compensation line for the
maximum compensation current, i.e. cross sections of 16 mm
2
for compensation lines up to a length of 200 m and 25 mm
2
for
compensation lines of more than 200 m in length.
X The compensation line must be made of copper or zinc coated
steel.
X The compensation line must be connected to the protective
conductor over a large surface area and must be protected
against corrosion.
X The routing of compensation lines should be carried out in such
a way that the distance between compensation line and signal
line remains as small as possible.
