Whether it came from Heraclitus in 470 B.C. or François de la Rochefoucauld in the 17th century, the adage “the only thing constant is change” usually directly affects the power quality level in a facility. Unless there is a conscious effort when changes are made to equipment and/or infrastructure, it often isn’t for the better. READ MORE

The power quality phenomena categories in IEEE Standard 1159 2009, “Recommended Practice for Monitoring Electric Power Quality,” are often used to define what to look for, how to look for it, and how to protect a piece of equipment from it. The following categories are excerpted from Table 2 of the standard: 1. Transients—impulsive and oscillatory2. READ MORE

A friend reminded me of the extensive flicker monitoring program that the Colombian utility commission required of electric utilities beginning in 2005. READ MORE

While conducting an investigation recently to determine why a piece of equipment in a telecom center was resetting occasionally from a perceived low-voltage condition, I actually was able to review the facility’s electrical drawings. Sometimes, the operations manager has no clue where they are. Other times, they are so marked up that I can’t decipher the latest changes. READ MORE

One of my responsibilities is to provide new employees with an abbreviated power quality course, so they know enough to relate the basic concepts to their particular job function. I do not want to overwhelm them by trying to turn them into power quality engineers. READ MORE

One power quality steady-state condition is known by two names: imbalance or unbalance. Given that the latter seems to be more commonly used in power quality and electrical motor documentation, I use “unbalance” in this article, with the caveat that “imbalance” can be substituted for those who prefer it.

Several of my articles recently have been about low-voltage direct current (DC) powered equipment and telecommunications systems vulnerabilities to power quality phenomena, especially with regard to transients, noise and other types of electromagnetic interference (EMI). READ MORE

“Going Green” is applied to construction, vehicles, recycling, or just about any activity or product. If you search for it on Google, you will get more than 200 million hits. In articles last year, we covered establishing an energy-efficiency program and conducting energy audits, both ways to make the facility more green. READ MORE
