Grid Measurement and Protection
module GMP232
Bachmann electronic‘s Grid Measurement and Protection module, the GMP232, is part of the M1 controller
and enables safe, reliable, and fast measurement for
three phase electrical networks. The GMP232 also
provides a number of monitoring functions for generator and grid protection. Up to two circuit-breakers/
trip circuits are triggered by the m
­ odule directly via
relay outputs. The continuous m
­ onitoring of grid harmonics up to the 50th harmonic can be used for direct
responses as well as for evaluating the power quality.

The GMP232 module is provided with an integrated
real-time data recorder for high-precision recording of
up to 16 measuring channels during alarm/protection
events. Error events are continuously recorded and
stored within the module‘s internal memory along
with precise time stamps. 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 is fully integrated into the Bachmann
SolutionCenter. User-defined configurations are easily
created and stored for later use. Both measured
channel values and derived values are made available
directly within the user interface. Commissioning and
fault analysis are simplified with tabular, phasor, and
time sequence displays. Event logs and recorded time
sequences can be exported as CSV or COMTRADE file
formats. The integrated simulation monitoring functions simplifies the configuration of protection and
monitoring functions.
