About Product

The Vitrek PA910 Series Precision Multi-channel Harmonic Power Analyzer is actually three power analyzers in a single chassis with a single user interface.  These are called Virtual Power Analyzers (VPA) or Channels.  Channels may be configured in any one (or none) of the 3 VPAs.  Each VPA may be configured for up to all channels installed and is independently configured for multi-channel wiring configuration, signal filtering, default measurement coupling, display results smoothing and significant digits, VA/VAR combine method and efficiency grouping.  Vitrek PA910 Series is the most powerful, accurate and flexible power analyzer available on the market today available with 0.045% power accuracy.  These new products provide faster sampling rates, bandwidth performance and greater harmonic frequency, yet still easy-to-use and affordable.

The PA910 power analyzers offer expanded power analysis options. The PA910 offers ultra high 0.045% power accuracy for all channels.  In addition, the PA910 provides easy channel selection for the user while offering 100 full precision readings per second and measurement bandwidths sufficient to handle 5 MHz waveforms.

Product Functions

  • Each virtual power analyzer may be configured as having one of the following synchronizations to the other virtual power analyzers
    • Totally asynchronous to the other virtual power analyzers in all aspects
    • Fully synchronous to another virtual power analyzer (identical sampling, measurement period and fundamental frequency)
    • Totally asynchronous to the other virtual power analyzers but using the fundamental frequency established in another virtual power analyzer
  • VPA Multi-Channel Wiring: Each VPA may be configured as 2ø3w (2 Ch), 3ø3w (2 Ch), 3ø3w (3 Ch), 3ø4w (3 Ch)
  • Front panel results screens
    • Power Data Screen
      • This displays V, A, W, VA, VAR and PF data for any selected channel or group of channels known as a Virtual Power Analyzer™ (VPA). Up to three different VPAs can exist in a single PA910. In addition to the primary data, peak readings, phase, CF and other parameters are also available.  Integrateddata results (WHr) can also be controlled and viewed from the Power Data Screen (See photo section)
    • Custom Data Screen
      • For users with unique data requirements, Custom Data Screens can be built with a spreadsheet application and downloaded to the PA910 via interface or USB drive (See photo section)
    • Harmonics Screen
      • To meet advanced power harmonics requirements, the PA910 displays up to 500 harmonics even at aviation power frequencies. The chart can be set to show linear, relative linear, logarithmic or relative logarithmic amplitudes.  Additionally, eight harmonics can be selected for numeric display of amplitude and phase by touching the harmonic bar of interest.  The user may also import harmonic limits, which when enabled will show out of tolerance harmonics in red above the limit line (See photo section)
    • Scope Screen
      • Scope View offers waveform acquisition and analysis similar to a digital scope. Up to six signals can be displayed, each havinguser selectable scaling, offset and color. Time-base, trigger and trigger position are all user selectable. However, with amplitude accuracies as high as 0.03% – you are unlikely to find any other scope with this high level of precision (See photo section)
      • Cycle View represents a single cycle of the voltage and/or current periodic waveforms. The waveforms in photo section represent a full 10V square wave in blue and a 50:1 zoomed in view in red. Since the user sets amplitude and scaling – the result is an almost unlimited ability to amplitude zoom to expose fine detail. The sampling is forced to be asynchronous to higher order harmonics which leads to an effective sampling rate of 384MSPS (See photo section)
    • Vector View
      • A polar chart graphically displays the fundamental voltage and current vectors for the selected channel or VPA. For multiphase VPAs, the inter-phase voltages andnon-measured neutral phase vectors are displayed. The user may enable the display of and select the color of each vector up to a maximum of 10 (See photo section)
    • History Screen
      • The PA910 automatically maintains a continuous historical record of all non-harmonic measurement results and selected harmonics. Up to four user-selectable parameters can be graphically displayed using the History screen. The user can display the entire recorded period up to 397 days or zoom in as far as 1/64th of the total span. This provides an almost unlimited ability to amplitude zoom and includes a cursor which may be moved throughout the period with a touch of the screen (See photo section)
    • Standby Power Screen
      • The STBY POWER Screen gives you the ability to configure, start/stop, and view the results of low power measurements in accordance with EN50564:2011 para. 5.3.2, which is the recommended method for all low power measurements. The STBY POWER screen can be selected for view from any of the Main Data Screens by pressing the STBY POWER button. The PA910 has the ability to perform low power measurements independently in each VPA, so a single PA910 can perform up to 3 independent low power measurements. You select which VPA is being configured, controlled and viewed by using the VPA button (the leftmost across the top of the screen) (See photo section)
