Though not one for use of tweets or blogs or other forms of social media, I find it necessary sometimes to unclog the mind with a stream-of-conscious offloading of information. Hence, this article is not a singular theme but rather a series of information I learned at recent power quality standards meetings that seemed worthy to share.

When reviewing data from your power monitoring system, the 30,000-foot approach is a typical starting point.

Debates within the organizations that develop the power quality standards will probably continue for years about why “power” isn’t really the subject of the standards. The majority of the standards present how to measure, monitor, characterize, categorize and set limits on voltage. READ MORE

Not much time goes by without hearing, “My equipment used to work fine, but now it keeps locking up every so often. Our productivity is suffering big time.” My usual first questions are, “What has changed, and what are you doing differently?” The answer is usually “nothing” for both. READ MORE

Simple power quality problems often evolve into tangled webs that take a long time to unravel. As commercial and industrial systems become more integrated and rely more heavily on bidirectional information from multiple sources that are powered from different supplies, it can take considerable time to understand the interdependencies of how one part acts and reacts to the others.

When using a power quality monitoring instrument, there are some “gotchas” to watch out for; otherwise, your efforts can either be wasted or, perhaps worse, misleading by coming to conclusions that aren’t valid. The complete list is much longer than the one below, but these are among the top of the hit parade.

The meteorological events in the northeastern United States in October 2012 provided some interesting discussions on electric power.
