PQView 3.65.1 is available for download.  We completed nearly one hundred changes to PQView in upgrading from version 3.64.0 to 3.65.1.  Here are some highlights: 

• PQView Launcher: A shortcut to a new application now appears rather than the traditional shortcuts to the Power Quality Data Manager and the Power Quality Data Analyzer.  PQView Launcher allows you to use PQView without having write permission to the “Program Files” folder where PQView is usually installed, which provides better compatibility with Microsoft Windows Vista and Windows 7.  It also allows you to have more than one PQView application open at a time.  For example, you could have three instances of PQDA open at one time, each connected to a different PQView database.  PQView Launcher can be used to “trust” folders when using Microsoft Access 2007 or Access 2010; a database in a trusted folder can be opened without any warning messages from Microsoft Access.
• PQView Agent was upgraded to work on Microsoft Windows 2003 Server and Windows 2008 Server.
• Updates to Data Handlers: The following data handlers were updated: IEEE Std 37.111 COMTRADE Folders, IEEE Std 37.111 COMTRADE Folders with No Mapping, Dranetz® PASS/PNDS Databases, Dranetz® ESS/InfoNode, Electro Industries® Communicator Log, and SoftSwitching® I-Grid® Web Site.
• Data Handler for Electro Industries Communicator Log:  This data handler was redesigned to load data log samples in batches.  This change means that large volumes of data will be imported up to 400% faster than when using PQView 3.64.0.
• PQ Event Roll: We modified the functionality of the Auto Zoom checkbox.  When checked, the time axis of all charts in the same PQ Event Roll window will be zoomed together.  That is, when one chart with time values for an x-axis is zoomed, all other charts will have their x-axis zoom modified to match the zoom of the chart that was just zoomed.  This feature has been requested by many users in the past.
• Optional Fault Location Add-in Module: The add-in module was updated to show the distance to fault in miles or kilometers when non-default values of line parameters are specified.  This makes it easier to use the add-in module with transmission line data.  For distribution circuits, the Fault Viewer was updated to allow one-line diagrams to be displayed that show only the line segments with phases that correspond to the fault phases.
• Derivation of ANEEL Indices: We revised the module in the PQView PQ Data Manager used to derive indices required by the Brazilian Electricity Regulatory Agency (ANEEL).  We also added an ANEEL report in the PQView PQ Data Analyzer.
• Steady State Trends Window:  You can create a new derived chart that cross tabulates the values in the trend chart by day.  This allows each day being plotted to be overlaid on top of each other day.

PQView was featured in a recent article written by Tennessee Valley Authority and EPRI for T&D World Magazine.

Presentations from the 2006 PQView Users Group Meeting in Knoxville are now available on-line.

The meeting focused on PQView 3.27.  The archive includes presentations describing how to import measurements from Schneider Electric ION Enterprise® Databases, the I-Grid® Server, Square D® System Manager Databases, Dranetz-BMI Power Xplorer® files, Dranetz-BMI InfoNode® Servers, and Fluke Scenario databases.   It also includes a presentation on the ONS Approach for Power Quality Management at the Transmission Level in Brazil.  Two cases studies were presented.  One was a study on power system interharmonics from a cycloconverter, and the other was the first use of PQView as part of an automatic distribution fault location system.
