Grid Measurement Module
GM260
The GM260 module enables the safe, reliable
and fast measuring of all relevant values for
three-phase electrical networks. Two separate
three-phase branches can be measured if there is a
common voltage measuring point. The grid variables
are calculated online in the module as True RMS
values including harmonics up to the 40th harmonic.
This is particularly useful for applications such as
for operational measurement on machines or the
energy monitoring in plants and buildings. As well
as functions for determining the active, apparent
and reactive power for each phase, two separate
4-quadrant energy counters are directly integrated
in the module.

The GM260 module is fully integrated in the
Bachmann SolutionCenter. Both the measured
channel values and also the derived values are made
available directly in the user interface.
