Voltage measurement connection diagram
For voltage measurement you can choose be-
tween the following connection schemes:
3p4w
3 phases 4 conductors
3p4wu
3 phases 4 conductors
3p3w
3 phases 3 conductors
For networks with no neutral con-
ductor with a balanced load
3p3wu
3 phases 3 conductors
For networks with no neutral con-
ductor with a balanced load
3p5w
3 phases 4 conductors
Measurement on an additional
conductor
1p2w
1 phase 2 conductor (180°)
INFORMATION
For the measurement inputs V4 and I4, no con-
nection diagram has to be configured.

Current measurement connection diagram
For current measurement, you can choose be-
tween the following connection schemes:
3p4w
3 phases 4 conductors, 3 current trans-
formers
3p5w
3 phases 4 conductors, 4 current trans-
formers
The fourth current transformer can
be used for the measurement of the
neutral conductor, for example.
3p2i
3 phases 4 conductors, 2 current trans-
formers
For networks with a symmetrical load.
3p2i0
3 phases 3 conductors, 2 current trans-
formers
Aron circuit for networks with no neutral
conductor. The third current is calcu-
lated
1p2i
1 phase 2 conductor, 2 current trans-
formers
