PQView 3.78.0 Released

PQView 3.78.0 is available for download. Here are some highlights for this release:

PQDIF File Importing: We made changes to allow import of observation records that have up to 16 million samples. In previous versions of PQView, no more than one million samples could be imported from a single observation record.

Automatic COMTRADE File Download using FTP: It is now possible to have PQView’s PQ Data Manager download COMTRADE files automatically from a remote FTP folder before data source import.

Better Multithreading: We revised PQView’s thread locking code to better support data source import of multiple PQDM instances running on the same computer that are run as a service using third-party applications like FireDaemon.

Updated Data Handlers: The following data handlers were updated: IEEE® PQDIF Annex C Folder, IEEE® COMTRADE Folders, SATEC PAS Database, ION Enterprise®/StruxureWare® Database, Schweitzer Engineering Laboratories® (SEL) Event Report Folders, and System Loads

CYMDIST Database Data Handler: We updated this data handler to compute impedance for line geometries modeled using the average geometric arrangement method and to process line sections that have load tap changer models.

I²T Calculations: PQView will now compute accumulated I²t for the phases involved in the fault.
