Compensated current clamp
Part No. L45-Z06
A special current measuring device is the
compensated current clamp by ZES ZIMMER.
It features electronic compensation of amplitude
and delay errors. Even at low current levels of
1A to 40A, measurement is exact in the frequency
range from 5Hz to 20kHz. Due to its high dynamic
common-mode rejection, this current clamp is also
very suitable for carrying out measurements at the
frequency inverter output.

Various methods of applying current to be measured
4 independent power measuring channels
The current and voltage paths
of the four power measuring
channels are all isolated from
each other and from earth.
This allows a high degree of
measuring freedom in many
different power measurement
applications.
The adjacent table shows vari-
ous types of wirings for grouped
and individual measurement
channels. The table also assigns
application examples for the
respective types of wiring.
Power measurement channels
1 and 4 can each be synchro-
nised to their input signals
(fundamental waves etc.)
independent of each other.
Channels 1 and 4 are then the
synchronisation references for
the other channels contained in
groups A and B.
This is a very useful method for
carrying out efficiency measure-
ments for equipment where the
input and output have different
frequencies, for example a
3-phase frequency inverter with
single-phase mains supply.
