Utility power quality standards

Companies that deliver electric power -- "utility companies", in American English -- have recognized over the last decade or so that their customers need to know what kind of power they can expect.

Here are some examples of published "power quality policies". If you know of others, please send us an e-mail at info@pqe.com.my.

• Pacificorp (Utah, U.S.A.)
  A reasonably informative set of documents, clearly based on IEEE standards. No guarantees; has been published since 1996. From the technical language, I would guess that these are aimed at engineers, not typical industrial/commercial customers.
   
• Office of the Regulator General (Victoria, Australia)
  This is a mixture of IEC and IEEE requirements. Although there is some "best endeavors" language here, this set of standards clearly contemplates some serious efforts by the electricity distributor to maintain power quality. Includes an interesting, but toothless, requirement for power quality monitoring.
   
• Useful power quality manual from Malaysia
  Tenaga Bhd Malaysia, the national power company, has made available an excellent guide on solving power quality problems at industrial sites; the guide is available for downloading at http://www.tnb.com.my/tnb/con_quality.htm
