Bachmann GMP232/x2 Grid Measurement and Protection Module

The GMP232/x2 enables the safe, reliable and fast meas

urement of all relevant values for three-phase electrical

networks. It also provides a number of monitoring func

tions for generator and grid protection. Up to 2 circuit

breakers/trip circuits are triggered by the module directly

via relay outputs. The continuous monitoring of grid har

monics up to the 50th harmonic can be used for direct

reactions 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 with a

high resolution time stamp. 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 geographically separated meas

urement and protection devices.

The GMP232/x2 module 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 dis

plays. Event logs and recorded time sequences can be

exported in CSV resp. COMTRADE format. The integrated

simulation function simplifies the configuration of protec

tion and monitoring functions.
