In this third part of my series on the most common power quality phenomena, I group several IEEE 1159 categories together under the general description of “distortion.” Though one might argue that all power quality phenomena result in distortions of the voltage sine wave, these are the more steady-state variety, including harmonics, interharmonics, notching, unbalance (or imbalance), voltage fluct READ MORE

Last month, we started the Top 10 in the power quality phenomena category with the most common disturbance: the rms variation. In second place are usually transients, those fleeting waveform changes that are far too brief to be seen by the naked eye in lighting. In certain cases, some power quality monitors aren’t able to capture them. READ MORE

From David Letterman to the FBI to Billboard magazine, the “Top 10” can be applied to just about any category, including power quality phenomena. Although it is a highly subjective process, there is some merit in being more than just familiar with them. READ MORE

Reading through the websites and marketing Material of the major power quality instrument manufacturers in the hopes of figuring out which power quality monitor to buy can leave one feeling confused, frustrated and wondering which way to turn. READ MORE

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

You finally were able to buy a power quality monitor to determine what is causing your customers’ equipment to misoperate. From the frustration of waiting for Windows to reboot to the inconvenience of cleaning out solidified plastic pellets when the extruder stopped extruding, power quality phenomena problems range from the annoying to the expensive.
