It can save hours of work and a lot of money While doing some construction work recently, I needed a tool that was in my truck, but didn’t feel like going to get it. So I tried to “make do” with what I had in my toolbox. Needless to say, the job took twice as long and didn’t come out the way that I wanted. So I ended up going to get the right tool anyway.

Power supply design determines an appliance’s energy profile On the plane coming home from the Institute of Electrical and Electronics Engineers Power Engineering Society meeting, I was proofreading a paper that proposed to convert our way of looking at power-quality phenomena from sags, swells, transients and harmonics to a single unified parameter, energy.

Inrush and the laws of physics Trying to explain power quality phenomena and even electrical concepts in general often results in attempts to translate them into a different domain, such as the mechanical world. Trying to come up with the mechanical equivalent of VARs (volt ampere reactive) is still elusive. READ MORE

PQ safety is often overlooked, despite the danger Part of any power quality seminar material should cover the aspects of safety, especially for anyone who must connect/disconnect the voltage and current probes for power quality monitors. An excellent document to refer to is the NFPA 70E Standard for Electrical Safety in the Workplace, 2004 edition. READ MORE

Power quality problems lurk Stories about an increase in productivity in the commercial and industrial worlds attributed heavily to the growth in information technology (IT) equipment. In fact, this number has been put at $46 billion for the 2003 fiscal year. The 2002-2003 productivity report, according to the U.S. READ MORE

A different kind of harmony The Stevie Wonder/Paul McCartney classic “Ebony and Ivory” asked why we can’t live together in harmony. Though I am pretty sure that song wasn’t the inspiration for this, three of the largest and most influential standards-making groups in the world have been trying to live in harmony for the last few years in the power quality realm.

A different kind of poison Every time I see the lights on a Christmas tree blinking on and off, I am reminded of the old adage, “One person’s medicine is another person’s poison.” Flickering lights in an office, factory or residential home can be more than an annoyance. READ MORE

Hospitals have a priceless ‘product’—human life When people think of high-reliability facilities, most often it is the financial data centers and the semiconductor plants that come to mind. While these types of facilities can experience very costly downtime, the medical facilities have a far more valuable “product”—human life. READ MORE
