IEEE Std. 1159.3

The purpose of the IEEE Std. 1159.3, also known as the Power Quality Data Interchange Format (PQDIF), is to develop a recommended practice for a file format suitable for exchanging power quality-related measurement and simulation data in a vendor-independent manner.

The purpose of this Web site is to bring together all the resources on the PQDIF standard. By forming this PQDIF Users Group, it is hoped that interested parties can obtain the information required to develop or manufacture power quality products that are compliant with the PQDIF standard.

Membership in this Users Group is free. However, you need to obtain a username and password to gain access to various areas of this site by clicking on the "New User" button at the top of the screen.
