IEEE 1159.3 PQDIF Task Force


The IEEE 1159.3 Task Force is revising IEEE Std 1159.3-2003, IEEE Recommended Practice for the Transfer of Power Quality Data (PQDIF). The task force plans to complete the majority of the revision work in 2015 and 2016 and to begin balloting in 2017.

P1159.3 PAR


Recommended Practice for Power Quality Data Interchange Format (PQDIF)


IEEE 1159.3 provides the power quality industry with the specification for PQDIF, which is an open and accepted data format standard for the transfer of power quality data between instruments and computers. This transfer standard allows the processing and analysis of power quality measurements using multi-vendor and multi-device data. Wider acceptance of PQDIF as a power quality data transfer format will significantly add to the value of power quality monitoring and open new opportunities for the resolution, planning, and understanding of power quality activities. Being able to exchange data between software systems will allow other functions needed in a power quality monitoring campaign, including validation, trending, comparison, overlay, and more.


IEEE Std1159.3 is in much wider use today than when it was first published in 2003. Although it was reaffirmed in 2008, the field of power quality monitoring has evolved in the past decade, and the changes in this domain are not reflected in the 1159.3 standard itself. This project will update the existing document using the experience gained in eleven years of PQDIF applications, correcting errors, clarifying known points of confusion, and augmenting its list of IDs and values used in the modeling of power quality monitoring instruments and data.


  1. To complete editorial changes and technical corrections/clarifications to the 2003 edition of IEEE Std. 1159.3
  2. To add new ID values for existing PQDIF tags
  3. To add new tags and ID values
  4. To add new quantity types
  5. To add an annex on the representation of PQDIF in XML
  6. To add an annex on PQDIF and its relationship to IEC 61850
  7. To add an annex on PQDIF and its relationship to IEEE C37.111 COMTRADE
