“The latest version PQDiffractor is now available for download online.”

But what is actually the current version of the PQDiffractor?

Power Quality software, such as PQView 4 or DranView 7, provides you with a smooth interface for viewing PQDIF and COMTRADE files. In addition, the software solutions offer a wealth of other functions, for example for monitoring and analyzing power quality. But what if you are afraid to invest in software because you only need a view for rough analysis? There are two possible solutions for this. First, the latest version of PQDiffractor and second, a multifunctional web interface.

The current version of PQDiffractor works as a PQDIF and COMTRADE viewer for viewing, searching, diagnosing and converting PQDIF and COMTRADE files. And this free of charge.

Option 1: The viewing and analysis of the data using the current version of PQDiffractor.

PQDIFFRACTOR

If you only need one viewer, PQDiffractor® the free PQDIF and COMTRADE viewer is just what you need.

Main functions of current version PQDiffractor:

  • Reading binary PQDIF files using IEEE Std 1159.3-2003 specifications
  • Reading of ASCII or binary COMTRADE files using the specifications of IEEE Std C37.111-1991 or C37.111-1999
  • View lists of the data source records in each PQDIF file.
  • Displaying lists of analog and digital channels from COMTRADE configuration files
  • Create interactive graphs from PQDIF observations with channels of any size type.
  • Displaying samples from analog COMTRADE waveforms and digital status channels
  • Exporting the displayed observations to Microsoft Excel as CSV files

And you have read correctly. The current version PQDiffractor is free of charge and connects you to the latest MAVOWATT, HDPQ, LINAX PQ3000, LINAX PQ5000, LINAX PQ1000 and LINAX PQ5000-MOBILE devices without any problems.

Option 2: The viewing and analysis of the recorded PQ data via integrated web-browser.

Web Browser

No external software is required for parameterization of the measuring device or evaluation of the measurement results. Das Webinterface stellt alle notwendigen Funktionen zur Verfügung. These functions can be accessed via end devices (e.g. smartphone, tablet, laptop, desktop, server via LAN or WLAN interface) using an IP address. A responsible WebGui guides the user through the menus. The simplicity of operation is to be emphasised. Because the advantage is obvious: There is no need for external software that causes additional headaches for administrators. And this for mobile as well as stationary applications. And it’s Cyber Secure.

Fields of application for the current version of the PQDiffractor as well as the integrated web browser

  • Smaller distribution grid systems
  • Municipal utilities
  • Energy generators (e.g. large PV plants, wind farms, hydropower, coal and gas, nuclear, etc.)
  • Industry (e.g. semiconductor, steel, automotive, pharmaceutical, aviation, etc.)
  • Infrastructure (e.g. rail, metro, airport, etc.)
  • Data centres
  • Clinics
  • Laboratories
  • Institutes
  • Higher education institutions
  • Universities
  • Authorities
  • Military
  • Applications to be reached remotely via VPN
  • etc.

Accuracy of the measurement questioned.

Measuring instruments are usually classified according to standards and accuracy. Accuracy is an important indicator for being able to usefully build on a solid measurement result in the analysis and its resulting measures. However, it can be observed that although the measuring devices used correspond to a required accuracy class, the necessary sensors are often less in focus.

It can be seen that although class A measuring devices used in power quality applications correspond to a data sheet accuracy of 0.1% for U/I and 0.2S at the energy meter, upstream current transformers are often designed significantly worse (e.g. 0.5% or worse). And this is apart from the fact that not only accuracy plays a role in power quality measurements, but also the inevitable compatibility against harmonics – one of the modern and growing main players in power quality.

Actual situation

In a large urban city, the technology for supplying fresh water is getting old. Although the pumping stations and the infrastructure are in good condition, the maintenance and repair costs are continuously and extremely increasing. Electrical monitoring of the entire system is only available to a limited extent, and if so, only partially. Read more

 

With the “PQ-Easy Report”, statistical reports can be generated directly from the measuring instrument, either according to standard or also user-specific. And this completely autonomously and detached from proprietary software solutions that make life difficult for many users as well as the IT department.
