If required, you have the option to determine events, Flicker and Harmonics, of the
phase-to-phase voltages.
Check the respective option.

Note
If this option (calculation) is checked, you must enter the phase-to-phase
voltage as the rated voltage V
N
in ‘Settings – Nominal / Limit values’ (e.g.
400 V in the 230 V P-N network).

Four-Wire Network: Three-Wattmeter Method with N Conductor Voltage and N
Conductor Current
This is the standard measurement configuration for three-phase networks with 4 voltage
and 4 current sensors.
Figure 3-5 shows the circuit diagram for 4-wire network (3-wattmeter method) with N-
conductor voltage and N-conductor current.
