PQDIF and COMTRADE are two industry standard file formats for Power Quality and oscillography data. PQView 4’s Power Quality Data Manager Service ( PQDMS ) is a data concentrator that allows for direct communication with many popular power measurement devices. It is also compatible with the PQDIF and COMTRADE file formats.
If you just need a file viewer, PQDiffractor® is a free PQDIF and COMTRADE viewer written by Electrotek Concepts, Inc . for viewing, browsing, diagnosing, and converting PQDIF files and COMTRADE files, and is a free software download from pqview.com.
PQDIF, which is an acronym for Power Quality Data Interchange Format, is a file format specified in IEEE Std 1159.3 that is used to exchange voltage, current, power, and energy measurements between software applications. PQDIF is maintained by the IEEE P1159.3 Task Force of the IEEE Working Group on Monitoring Electric Power Quality. This work is sponsored by the IEEE Power Quality Subcommittee.
