Grid measurement module
GMP232/x Grid measurement and
protection module
The GMP232/x module enables the safe, reliable
and fast measuring of all relevant values for threephase electrical networks. It also provides a number
of monitoring functions for generator and grid
protection. Up to two circuit-breakers/trip circuits are
triggered by the module directly via relay outputs.
The continuous monitoring of grid harmonics up to
the 50th harmonic can be used for direct responses
as well as for evaluating the power quality.

The module is provided with an integrated real-time
data recorder for the high-precision recording of up
to 24 measuring channels during alarm/protection
events. Error events are recorded continuously and
stored permanently with a high resolution time
entry. The internal time base of the module can
be synchronized to an external time source (e.g.
IEEE 1588 Precision Time Protocol), which supports
the analysis of the data from spatially separated
measurement and protection devices.

The GMP232/x is fully integrated in the Bachmann
SolutionCenter. Configurations can be created simply
and stored for later reuse. Both the measured
channel values and also the derived values are made
available directly in the user interface. Commissioning
and fault analysis are simplified with tabular, vector
and time sequence displays. Event logs and recorded
time sequences can be exported in CSV or COMTRADE
format. The integrated simulation function simplifies
the configuration of protection and monitoring
functions.
