PQView 3.76.0 Released 

PQView® 3.76.0 is available for download. This version includes more than 160 changes that result in improvements in nearly all components of the PQView application, including the installation program, 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:

Easier Support of PQDIF Import in Windows 7: Many users have begun to use PQView on a Windows 7 computer, or the related Windows Vista, Windows 8, Windows 2008, or Windows 2012.   We made changes in the PQView installation program that will enable more complete import of IEEE PQDIF files when using these later editions of Microsoft Windows without needing administrator permission on your computer during normal usage. 

Parallel Data Source Importing: PQDM has some improvements that make the clean-up of temporary files less problematic when using PQView Agent to import more than one PQView data source at the same time.

Support for SQL Server 2012: You will find a T-SQL script that will ship with PQView 3.76.0 that can be used to convert an existing PQView database for full use in SQL Server 2012. 

COMTRADE File Data Handler: You can now specify more than one COMTRADE analog channel to be the source for a PQView waveform channel.  For example, if you are using PQView with a digital fault recorder that has more than one line current that needs to be summed to comprise the current for Phase A, then you can do so by simply adding the second channel in the COMTRADE-to-PQView channel map configuration file.  We converted some pop-up error messages to data source log messages.  We now allow you to override the line frequency in the configuration file, and allow you to import kW, kvar, and kVA if the COMTRADE file includes these power channels. 

ION Enterprise Data Handler: We added support the optional ION Enterprise Data Handler for PQView to allow import from Schneider Electric StruxureWare databases.

Reactance-to-Fault Add-in Module: In this optional add-in module used for automatic fault location, we added new e-mail notifications for negative-sequence overcurrent with no SCADA correlation, zero-sequence overcurrent events with no SCADA correlation, and events with missing current.

InfoNode Summary Window: We added a new window that can be used to show the status of all DataNodes associated with one or more InfoNode data sources in the PQView database.  The window lets you see the name, description, last connection time, status, health, serial number, model, version, IP address, and nominal voltage  for each DataNode.  Additionally, you can activate or deactivate multiple DataNodes at one time from within PQDM.  You can also use PQDM to request the InfoNode to poll one or more DataNodes on demand, and to view the InfoNode log.

New Chart Options: You can now specify the default chart size (small, medium, or large) and default zoom mode (horizontal, vertical, or horizontal & vertical) for interactive charts.

PQ Event Roll: We added a new derived chart that allows you to overlap voltage waveforms for a multi-cycle recording into a one-cycle window.  Also, you can now make frequency calculations for shorter measurements because we ignore just the first cycle and last cycle of the measurement before looking for zero crossings.  Previous versions of PQView ignored the first three and last three cycles.

Steady-State Trends Window: You can now add text annotations to the trend charts from the event descriptions or system event details. Also, you can use the window to display specific dates only, allowing easy comparison of the data logs for one day to another day.

Steady-State Load Forecast Tool: The load forecast tool, which can use temperature and/or humidity data along with historical load measurements to predict future load growth, was updated to be more flexible with correlation between load and weather data. A temperature sample needs only to be within fifteen minutes of a load sample in order to be compared.

PI Explorer: You can now query trend values from a PI Server without importing them into a PQView database.

Rapid Voltage Change Event Analysis Window: We made many changes to the tool that allows you to create RVC Event Lists and to make an RVC Summary Report to the specification of the Norwegian Water Resources and Energy Directorate.


PQView 3.75.6 Released

PQView® 3.75.6 is available for download. This version is a minor update over PQView 3.75.5.  It corrects a bug that prevented correlation of records from an OSIsoft PI System with PQView events during data source import.  Also, a change was made in the installation program that should make it easier to run PQView for the first time without being an administrator or power user on Windows 7 computers.  Finally, the Data Source Import Report e-mail will be sent with a “high importance” flag if errors are encountered during data import.


Electrotek Concepts Partners with OSIsoft

Electrotek Concepts® is now a partner with OSIsoft® in developing software applications that are designed to work with OSIsoft products.  

At present, PQView can be integrated with an OSIsoft PI System® using PI OLEDB Provider and/or PI SDK. These functions are currently supported:

  • Import measurements from a PI System server to a PQView database
  • Export measurements from a PQView database to a PI System server
  • Correlate SCADA operations stored in a PI server with power quality and fault events stored in a PQView database
