SECTION IV
CONNECTION TO POWER SYSTEMS
WARNING!
This Instrument requires connection to dangerous voltages.
Use suitable safety accessory.
This instrument can be connected to the 3ϕ system in 3 ways:
3ϕ four wire system L1, L2, L3,N; I1, I2, I3
3ϕ three wires system L12, L23, L31; I1, I2, I3
Aaron (2 wattmeter) 3ϕ connection L12, L32, I1, I2
The actual connection scheme must be defined in METER Configuration menu (see Fig 19
below).
Fig. 19: Meter Configuration Menu
Use LEFT and RIGHT keys to select the appropriate connections scheme.
When connecting the instrument, it is essential that both current and voltage connections
are correct. In particular, the following rules must be observed:
Current Clamp-on current transformers
The arrow marked on the Current Clamp-on current transformers must point in
the direction of current flow, from supply to load.
If a Clamp-on current transformer is connected in reverse, the measured power in
that phase would normally appear negative.
Phase Relationships
The Clamp-on current transformer connected to current input connector I1 MUST
measure the current in the phase line to which the voltage probe from L1 is
connected.
Wiring connections are shown in Fig. 20, Fig. 21 and Fig. 22 below.
On systems where the voltage is measured on the secondary side of a voltage transformer
(say 11 kV / 110 V), a scaling factor taking account of that voltage transformer ratio must
be entered in order to ensure correct measurement (see Section III 3.2.5 METER
Configuration).
