The word "government" often invokes “regulation” (at least until it was replaced with “bailout”). However, governmental regulation of power quality is basically nil in North America, especially in the United States. This is in contrast to other places, where aspects of power quality beyond just nominal voltage range and frequency are covered. READ MORE

Recently, I was on a panel at a conference on power quality and reliability-related issues. Somewhat amazing was the amount of discussion on that buzzword that keeps going and going: smart grid. I thought my column, “Smarter than a Fifth Gridder,” in the March 2009 issue would be the last I would deal with it. But that conference and a quick search on Google set me straight. READ MORE

A few months ago, we answered a customer’s question about what equipment might be affected by a particular type of power quality phenomenon. The answer was based on Table 4.2 from IEEE Std 1159 Recommended Practice on Monitoring Electric Power Quality, and it seemed to be a logical way to address what can be a fairly complex process.

On New Year's Eve, I visited someone in the hospital. I was struck by two things. First, there were patients and staff members in the wards, as, unfortunately, illness doesn’t follow a calendar. But overall, the hospital seemed nearly deserted, with most offices and labs closed, no one in the cafeteria, and only the occasional healthcare worker or security guard roaming the hallways.

When most people think of finding the source of power quality problems, they imagine a meter or monitor with half a dozen or more wires connected to the voltage bus or terminals, along with three or four current transformers (CTs) clamped around either the bus bars or the wires. READ MORE

Although the hyperbole of the recent elections is past us, one of the buzzwords that gained momentum in the process was the term “smart grid.” I agree with those in the electric utility industry who take exception to such a concept, with all the implications associated with it, including that the current grid is “dumb” and the smart grid will solve all our power problems.

The usual focus in this column is what those squiggly waveforms are called and what causes them. Sometimes the focus is even what gets rid of them. READ MORE

Many school systems have educational programs on energy conservation, recycling and becoming more green. Kids come home full of excitement and try to get their parents to do their part. Does the school itself lead by example? A tour through many educational facilities often finds the opposite. READ MORE

Several times recently, someone has asked why two different instruments reported the same values for watts (W) and volt-amperes (VA), but they don’t show the same values for volt-ampere-reactive (VAR). A quick Internet search will turn up a lot of explanations why some instruments are reporting the value incorrectly, but the sites have incorrect information about how to calculate VARs. READ MORE
