17 CONNECTION DIAGRAMS
For measurements requiring connection of the earthing cable, the
corresponding option in the active measurement menu must be correctly
configured
17.1 THREE-PHASE CONNECTION WITH NEUTRAL
If the proper clamps are used, this allows measurement of the voltage and current of the three
phases and neutral, voltage between neutral and earth and leakage current.

17.2 THREE-PHASE CONNECTION WITH NEUTRAL
Measurement of the voltage and current of the three phases and leakage current.
Fig.17-2.- Connection for measurement of a three-phase system without neutral and with earth
17.3 THREE-PHASE ARON CONNECTION
Measurement of the voltage of the three phases.Measurement of the phase current L1-L3 and
calculation of current in L2.Measurement of leakage current.
