Bachmann Grid Measurement and Protection Systems

Safety and efficiency of the electrical energy supply

The portfolio begins with the GM260. which is suitable for energy

monitoring according to ISO 50001. operational machine control,

and power consumption related fault detection. A remanent 4Q

energy meter per circuit calculates active and reactive power

independently from the PLC.

For use in power generation systems and virtual power plants,

the GMP232/x2 family adds extremely fast and accurate continuous

RMS measurements, fundamental extraction, and symmetrical

components while meeting the overvoltage category CAT IV according

to IEC 60664. Outstanding frequency accuracy of 1 mHz, with 12

updates per cycle ensures easy tracking even within weak microgrids

or island grid formation. Configurable digital protection functions ensure

grid code compliance and system self-protection.

The built-in fault recorder logs 10 kHz waveform data in COMTRADE

format according to IEEE C37.111 and IEC 60255-24. while also providing

continuous access to the samples by the PLC application programs.

Grid events are logged with globally-synchronized time stamps to analyze

any deviations with relation to other reference points. Harmonic analysis

directly on the module provides spectral data up to the 50th harmonic

along with related distortion factors, which allows an objective evaluation

of power quality.e GSP274 family adds automatic synchronization to the

busbar or grid combined with VDE-AR-N 4105 compliant network and

system protection (NS-Protection) that can withstand single faults.
