PQView 3.75.5 Released

PQView® 3.75.5 is available for download. This version includes more than 150 changes that result in improvements in nearly all components of the PQView application, including the charting engine, PQView Launcher, PQView Agent, PQView Explorer, the Power Quality Data Manager, and the Power Quality Data Analyzer. Here are some highlights for this release:

PQView Editions: PQView 3 is now delivered in two editions.  If you were using PQView before, you will have access to download PQView Enterprise.  PQView Enterprise has no hard-coded limit on the number of sites that can be stored in a single PQView database, and measurements can be stored in a Microsoft SQL Server database or in a Microsoft Access database.  If you were using PQView Express before, you will have access to download PQView Professional.  PQView Professional is limited to build a PQView database with no more than 50 sites in a single database, and the PQView database can be stored in Microsoft Access format only.  Other than those two points, the two editions of PQView are identical. 

Folder Options: You can now use the options window in PQView Launcher to specify alternative locations for the following special folders: the PQView Temporary Files Folder, the PQView Application Data Folder, and the PQView Personal Folder.  Previous versions of PQView hard-coded these folders to defaults specified by Microsoft Windows itself.  However, some companies limit write-access to these special folders, requiring administrator or power-user permission to run PQView.  This new PQView version allows you to specify the location of these folders. 

Multiple Downloads by PQView Agent: PQView Agent now allows you to specify whether multiple dial-up remote access connections are allowed. This means that PQView Agent could be used to download measurements from more than one Dranetz InfoNode or DualNode by telephone modem at one time.  If you enable this feature, we strongly suggest that you use a different IP address for each remote InfoNode. 

Updated Data Handlers: We improved the data handlers for importing the following data store formats: Cooper CYMDIST Network and Equipment Databases, Dranetz ESS/InfoNode Server, Dranetz DDB Files, Electro Industries Log Databases, New York ISO System Load Data, NOAA Daily Geomagnetic Data, PJM Interconnection System Load Data, Qualitrol Q-Wave Information System (QIS) Databases, SATEC PAS Databases, Schneider Electric ION Enterprise Databases, SoftSwitching Technologies I-Grid Web Site, and the SCADA Database for APC. 

PQ Event Roll: We added new derived charts for displaying form factor and crest factor from waveform samples.  We also added check boxes for enabling the computation and display of point-by-point and cycle-by-cycle calculations for symmetrical components.  We improved integration of the PQ Event Roll and the Fault Viewer. 

Zoom Window on Interactive Charts: The zoom window introduced as a chart option in PQView 3.68.0 can now be toggled on or off by pressing the <Ctrl><Z> key combination when viewing an interactive PQView chart.  This zoom window appears at the bottom of interactive charts in the PQDM and PQDA. 

Fault Location Add-in Module: We updated the Fault Location Add-in Module to provide residual overcurrent (that is, zero-sequence overcurrent) and “subsequent event” detection and notification.  We updated the Fault Viewer in PQDA after working with numerous PQView users in the last few months, making many improvements based around usability.
