    Recording and diagnostics under all conditions

    Resistant to any conditions, the Sonel PQM-700 power quality analyser is an effective device for analysing and recording network parameters. Based on advanced technology, the Sonel PQM-700 power quality analyser is effective for measuring, analysing and recording 50/60 Hz power network parameters. It is also used to control the quality of electricity in accordance with the European standard EN 50160 and the Regulation of the Minister of Economy of 4 May 2007 on detailed conditions for the operation of the power system. The extensive measurement capabilities of this device will be appreciated by a wide range of users who need a portable device to check the quality of electricity. The Sonel PQM-700 meets the demanding standards of the IEC 61000 standard for Class S analysers related to measurement uncertainties and measurement methods. This meter model is intended for those users who do not need a Class A analyser, as the PQM-700 provides comprehensive measurements of power quality parameters in Class S in accordance with IEC 61000-4-30.

    Capabilities

    The analyzer provides comprehensive measurements of power quality parameters in class S, in accordance with IEC 61000-4-30, which guarantees high accuracy of results. Even when the temperature reaches -20ºC, the measurements are reliable and the device operation is stable - all thanks to the built-in heater.

    Thanks to the internal battery, the analyzer does not turn off after a power failure, but maintains recording - up to 6 hours. Data is recorded on a removable 2 GB memory card. Logs can be downloaded using a USB connection or using an external reader. Then they can be analyzed in free Sonel Analysis software.

    Displaying data

    All recorded parameters - including indicated events - can be easily read using the dedicated Sonel Analysis software. The advanced features of the application allow you to view the collected results and save them on your computer’s hard drive - in the form of raw data or reports.

    Sonel Analysis is constantly updated and developed. This means that the user will keep up with the latest requirements of norms and standards.

    Application

    PQM-700 fulfills its role in industry - in hands of electricians, maintenance services etc. - as a cheap, multi-functional load parameter recorder. It is also used by consumers and producers of renewable energy (wind farms, solar farms), where a 4-quadrant power analysis is required.

    SONEL ANALYSIS

    Sonel Analysis software – application delivered as standard accessory, indispensable for working with PQM-series analyzers. It enables:

    • analyzer configuration,
    • data reading from logger,
    • preview of network parameters in real time (with capability of reading via GSM modem),
    • deletion of data in the analyzer,
    • data presentation in tables,
    • data presentation in charts,
    • data analysis and generating reports in compliance with standard EN 50160 (reports) and other user defined reference conditions - also for PV micro-installations up to 50 kW, a breakdown  for active power states P>0, P<0 and P=0 and taking into account the graphs Q1=f(U1/Un) and cosφ=f(P/Pn),
    • independent support of multiple analyzers,
    • analyzer firmware updates.

    The software enables readout of selected parameters and their visualization in real time. These parameters are measured independently from the registration saved on the memory card. The user can view:

    • charts of voltage and current progression (oscilloscope),
    • charts of voltage and current over time,
    • phasor diagram,
    • measurements of multiple parameters,
    • harmonics and harmonic powers (estimating the direction of harmonics),
    • interharmonics.

    • Firmware PQM-700

      Changes in 1.16 version:

      New features:

      • Changed behavior of LOG led: now it blinks during recording and stays lit while waiting for trigger.

      Fixes:

      • Fixed incorrect recording of apparent power (10-min) for configurations according to Chilean standards.

       

      Changes in 1.14 version:

      New features:

      • Added recording of average currents (10-min), active and apparent power (10-min) for configurations according to Chilean standards.
      • Added recording of average currents (10-min) for configurations according to Polish and GOST standards.
      • Changed connection error detection threshold when checking sum of all currents (3-phase 3- and 4-wire circuits). To detect such error, the current sum RMS must be greater than 25% of the largest among all measured current channels (detection algorithm is now less sensitive).

       

      Changes in 1.12 version:

      New features:

      • Formatting of memory card restores default measurement configuration.
      • Added zeroing of the recorded frequency values if the reference phase voltage is too small.

      Fixes:

      • Minor bug fixes.
      Analyzers card will be formatted (all data will be removed). Before updating firmware all data should be saved. Upon completing the upgrade, and before initiating the data recording process, settings should be redone. This will help avoiding discrepancies in recorded data.
