multimess F144 PQ

multimess F144-PQ stationary power quality analyzer and fault recorder

The power quality analyzer and fault recorder multimess F144-PQ for low, medium and high voltage networks is the central component of a system that can be used to solve all measurement tasks in electrical networks.

Detect possible malfunctions before they lead to a loss of production or defects in plant components. The multimess F144-PQ measures and monitors the network quality. It can be used as a power quality interface according to network quality standards, such as IEC61000-2-2 / EN50160 or to check technical connection guidelines, such as DIN VDE AR 4110 and DIN VDE 4120.

The network analyzer is designed primarily for measurements in industrial environments with up to 690 V (L-L) measurement voltage as well as for measurements in public networks.

The 5th current transformer input for measuring the residual current (RCM) as well as the frequency measurement of voltage and current harmonics in accordance with IEC 61000-4-7 from 2 kHz to 9 kHz are available as options. Especially this measurement from 2 kHz to 9 kHz is existential, since many clock frequencies of converters and inverters exist in this range.

Besides the possibility of standard evaluations, the multimess F144-PQ also has a high-speed disturbance recorder with a recording rate of 40.96 kHz/10.24 kHz as well as a 10ms RMS rms recorder. This makes an even more detailed evaluation of network interferences possible.

In addition, it is possible to freely program response thresholds for alarm messages or warnings. A device for increasing your operational safety.
