    Sonel Analysis 1.0

    „SONEL Analysis” software is an application used to work with PQM-701 power quality analyzer. It enables:

    • » analyzer configuration,
    • » reading data from the analyzer,
    • » network parameters check in real time,
    • » data deleting in the analyzer,
    • » data presentation in tables,
    • » data presentation in diagrams,
    • » data analysis according to EN 50160 or according to user defined conditions,
    • » independent service of multiple analyzers,
    • » software upgrade through the Internet.

    Analyzer configuration

    The software enables configuration of all analyzer’s parameters. The configuraton is made on the PC computer and later transfered to the analyzer. The configuration settings can be stored on hard drive or other data storage devices to be used later.The software enables the configuration of:

    • » wthe choice of Measurement Points and memory assigment to each Measurement Point,
    • » analyzer time settings,
    • » keyboard lock,
    • » PIN code security,
    • » averaging time setting,
    • » choice of current and voltage transformers,
    • » trigger mode choice (immidiately, after an event or according to the scheduler),
    • » choice of clamp’s type, setting of additional parameters registration in N and PE channels,
    • » choice of network type, for which the analyzer will be used.

    The analyzer has four independent Measurement Points. Each Measurement Point can be set individually to perform four different types of registration without need to change analyzer’s configuration.

    For each Measurement Point the following settings can be made:

    • » cwheather the analyzer shall work according to EN 50160 or according to user defined conditions,
    • » for each registration user can define, which network parameters shall be registered,
    • » for each parameter user can define wheather the analyzer shall register average, minimum, maximum or instantaneous values,
    • » the limits beyond which the analyzer will record the event can be defined.

    Recent data reading

    “SONEL Analysis” software enables reading of selected parameters and their graphic presentation in real time.These parameters are measured independently of the registration saved on the memory card. User can check:

    • » wvoltage and current diagrams (oscilloscope),
    • » diagrams of voltage and current in time function,
    • » scope phasor,
    • » different parameters values,
    • » harmonics and harmonics’ power.

     

    Data analysis

    With “SONEL Analysis” software user can read data stored on the memory card and analyze them. Data from the analyzer can be stored on hard drive and be used later. This feature enables data archiving.

    The user can analyze the data from the device.There is a choice of:

    • General – all data are shown with dots (Measurements, Events and Oscillograms),
    • Measurements – all measured values registered in averaging time are shown with dots (voltage, frequency, etc.),
    • Events – all detected events are shown with dots (dips, swells, interruptions, etc.).
