IEEE 1159.3-2003

This recommended practice will develop a criteria for the transfer of power quality data between instruments and computers. This data includes raw, processed, simulated, proposed, specified and calculated data. The transfer criteria will include the data as well as appropriate data characterization parameters, such as sampling rate, resolution, calibration status, instrument identification, and other pertinent or desired characteristics or data. The recommended practice will provide criteria guidelines for transferring power quality data.

The power quality industry lacks an adequate open and accepted data format standard for the transfer of power quality data between instruments and computers. This lack of a transfer standard significantly inhibits the analysis process of power quality assessments using multi-vendor and multi-device data. The analysis functions of signature patterns, history, and multiple measurement points are almost non-existent because of the lack of the ability to transfer data from multiple sources to a common analysis computer. Acceptance of an industry standard power quality data transfer format will significantly add to the value of all power quality data and open new opportunities for the resolution, planning and understanding of power quality activities. This will serve to satisfy the validation, trending, overlay, spectrum analysis, and other needs of client activities.

New IEEE Standard - Superseded. This recommended practice defines a file format suitable for exchanging power quality related measurement and simulation data in a vendor independent manner. The format is designed to represent all power quality phenomena identified in IEEE Std 1159 TM -1995, IEEE Recommended Practice on Monitoring Electric Power Quality, other power related measurement data, and is extensible to other data types as well. The recommended file format utilizes a highly compressed storage scheme to minimize disk space and transmission times. The utilization of globally unique identifiers (GUID) to represent each element in the file permits the format to be extensible without the need for a central registration authority.
