Power Quality
- A Power Quality Primer
This paper discusses the basic issues surrounding power quality, from basic definitions to grounding to harmonics, in general terms. Suggestions on wiring techniques and power quality are also included. - Two Modern Power Quality Issues – Harmonics & Grounding
A moderately technical discussion of the mechanics of harmonics and improper grounding, the damage they cause, and what can be done about it. - Power Quality and Your Computer
Innovations article by Martin Conroy, President, CPC, Inc. - Are You Ready for the Electrical Needs of Today and Tomorrow?
A power quality design adds only 1-2% to the cost initial of a building but can save many times that amount in downtime. This is a short list of suggestions to improve the quality of power, intended to spur further reading. - Wiring for Power Quality
A table illustrating some of the new wiring practices recommended to achieve a high level of power quality. - An Abbreviated Bibliography of Power Quality Information Sources
A short listing of printed sources of information on power quality issues. - Have a Good Power Quality Story to Tell?
Engineers, Building Operators, Electrical Contractors, Plant Operations Personnel: CDA is interested in hearing how your company designs its facilities to avoid power quality problems, or took steps to alleviate them.
