LINAX PQ5000
Stationary PQ measurement technology in class A as top-hat rail mounting.
The LINAX PQ5000 combines the characteristics of a normative power quality measurement device with functions for energy consumption and condition monitoring.
The modern, multi-lingual design allows operating and parameterizing the device via website or the high-resolution color TFT display (800x480px). The integrated webserver provides remote acquisition, visualization and analysis of measured data. No additional software is required.
- Independent certification acc. IEC 62586-2 by Federal Institute of Metrology METAS
- Support for standardized, manufacturer independent PQDIF format acc. IEEE 1159.3
- Definable event recording duration: Up to 6 seconds for samples and 3 minutes for RMS values
- Event display via website with time zooming function and reading of values
- Report generation via the device’s web interface (PQ Easy Report)
- Cyber security (OT) / cyber protection
- Optional PME control center: PME sensors for recording up to 100 currents via radio signal
- Power mean-values with trend-analysis for preventing load-peaks
- Load profile storage with fluctuation range (min/max) per interval
- Active energy class 0.2S, Reactive energy class 0.5S (HT/LT, demand/delivery), configurable resolution
- Further mean-values and meters with selectable base quantity
Power quality analysis
The device is intended to be used for a permanent power quality assessment according IEC 61000-4-30 Ed.3 in class A. The recorded events (voltage sag, voltage swell, voltage interruption, RVC, current swell, frequency change and homopolar voltage) serve both to prove that disturbances have occurred and to search for the origin of the disturbance in order to increase security of supply. Using the statistical voltage and current quantities, compliance with supply contracts or internal requirements can be verified. Assessment according EN 50160, IEC 61000-2-2/4/12, IEEE 519, GB/T or self-defined limits can be carried out after the measurement, corresponding conformity reports can be created via the device website (PQEasy-Report).
