The Voltage Quality Workgroup (VQWG) addresses issues regarding the quality of voltage supplied to the
customers equipment from the electric power system.
Specifically, the VQWG maintains and updates the IEEE 1250 Guide. It is also a forum for thoughtful
discussion and action about voltage level, fluctuation, sags (dips), swells, conducted noise, and anything
else that adversely affects the quality of supplied voltage. The "Voltage Fluctuation and Light Flicker"
(IEEE 1453) and "Voltage Sag Indices" (IEEE 1564) task forces report to the Voltage Quality Working
Group. While voltage distortion topics are discussed in general within the VQWG, the VQWG is not the primary
forum for addressing distortion issues. This is done within the Waveform Distortion (formerly Harmonics)
working group. Similarly, reliability and customer-side quality issues are also primarily addressed by other
IEEE forums.

Please feel free to participate in our IEEE Voltage Quality survey. This short, 5-10 minute survey is our means to understand
how electrical utilities around the world plan for, interpret, and resolve voltage quality issues on their distribution and
transmission systems.

The next scheduled meeting for the 1250 working group will take place at the 2007 IEEE Power Engineering Society general
meeting in Tampa, Florida. The precise meeting date and time are not yet known, but will occur sometime between
June 24 and June 28.
Both the working group and its task forces regularly meet with the IEEE Power Quality Subcommittee. See the
schedule for the subcommittee's next meetings.
