PA900 (Power Analyzer Mainframe with 4-channel Capability)


Brand: Vitrek
Model Series: PA900 Series

About Product

The Vitrek PA900 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. The Vitrek PA900 Series boasts an impressive array of precision power measurement capabilities, yet its color touchscreen user interface is refreshingly easy to use. The accuracy of the PA900 Series is truly world class-surpassing rival instruments costing triple the price. When it comes to speed and bandwidth, it tops the charts with 100 full precision readings per second and measurement bandwidths sufficient to handle 5MHz waveforms. For tackling tough power factor, low phase angle and high crest factor loads, it is certainly unbeatable. Offering full performance for crest factors as high as 30:1, the PA900 Series Precision Multi-channel Harmonic Power Analyzer places the advantage of superior power measurement capability.

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
  • Virtual power analyzer wiring
    • Each virtual power analyzer may be configured for the following multi-channel wiring configuration (depending on the number of channels assigned to the virtual power analyzer)
      • General (1 to 4 channels), 2ø3w (2 channels), 3ø3w (2 channels), 3ø3w (3 channels) and 3ø4w (3 channels. Total power (W, VA, VAR, and PF) and mean voltage and current results are available in addition to the results for each individual channel. Also, measurements of the inter-phase voltages (A-B, A-C and B-C) and the Efficiency Grouping (IN, MIDDLE and OUT)
  • 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 in a single PA900. 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 PA900 Series via interface or USB drive (See photo section)
    • Harmonics Screen
      • To meet advanced power harmonics requirements, the PA900 Series 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 PA900 Series 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 PA900 Series has the ability to perform low power measurements independently in each VPA, so a single PA900 Series 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)
