WAVECONTROL
Current monitoring
Monitoring flows of currents enables a
constant control of individual devices
and installation components.
Discrepancies or disruptions arising in
the electrical circuit can easily be eval-
uated as breakdowns. Targeted recti-
fying procedures can be taken.
The WAVECONTROL range of prod-
ucts convert sinusoidal/non-sinusoidal
AC/DC currents up to 60 A to stan-
dard analogue signals. The measure-
ment processes are based on 2 basic
principles.
One principle is alternating currents up
to 10 A ac and 50/60 Hz are mea-
sured using the transformer
process. The module is looped
directly into the measurement circuit.
A Hall-effect element comes in to
operation at 10 A ac/dc.
The potential-free wire is inserted
through the module, allowing currents
up to 60 A ac/dc to be measured.
Quite often, there are high-frequency
parts of signals on the wire to be
measured. In order to be able to take
these parts of the signals into consid-
eration, so-called TRMS converters
(TRUE Root Mean Square) are con-
nected to the Hall sensors. This
enables measurements up to 2 kHz,
independent of the shape of the
curve.
Standard signals (0...20, 4...20 mA,
4...20 A current loop supply, 0...10 V)
or a switch output are on offer.
