11.3.1 Voltage
Figure 11.2: Example of voltage and frequency measurements
Shown results for a single-phase system:
L1-L2 voltage between external conductors,
L1-PE voltage between external conductor 1 and protective conductor,
L2-PE voltage between external conductor 2 and protective conductor.
11.3.2 Line impedance
For further information, please refer to chapter 5.5 „Line impedance and prospective short-circuit
current“. The measuring method is the same, but the indication of the terminal voltage corres-
ponds to the IT system.
11.3.3 FI/RCD testing
The FI/RCD test is carried out in the same way as it is done in a TN/TT system (see chapter 5.3
„Residual current protection devices (FI/RCD)“. However, there is the following exception:
- The contact voltage measurement is irrelevant.
