IEEE Std 1159.3™-2019 specifies the Power Quality Data Interchange Format (PQDIF), which is a file format suitable for exchanging power quality related measurement and simulation data in a vendor-independent manner. Two critical “tags” to Table B.6 that were recommended in IEEE Std 1159.3-2003 but removed in IEEE Std 1159.3-2019: tagChannelDefnIdx and tagChannelGroupID are reinstated in this corrigendum.

This corrigendum addresses the omission of a required critical tag in Table B.6 that is used to link a channel instance to a channel definition and the omission of an optional tag that specifies the harmonic or interharmonic group of a channel instance.

IEEE Std 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.
