IEEE Std. 1159-3 PQDIF

PQDIF is a binary file format specified in IEEE® Std 1159.3-2003 that is used to exchange voltage, current, power, and energy measurements between software applications. PQDIF is an acronym for Power Quality Data Interchange Format.

IEEE 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. The next version of IEEE 1159.3 will include an annex with recommendations on how to represent PQDIF files in XML format.

PQDiffractor is a free PQDIF viewer written by Electrotek Concepts for viewing, browsing, diagnosing, and converting PQDIF files, and is a free software download from www.pqview.com.
