Last month's article touched briefly on the two of the most important laws in power-quality analysis and seemed to have generated enough questions that a more in-depth discussion might be warranted. READ MORE
February 2005
Seems like there is a new power-quality instrument being advertised in the trade journals each month-or at least devices that claim such capabilities in their ads. READ MORE

Adjustable speed drives or ASDs, are often categorized as "sensitive" to power quality phenomena, which means ASD could also stand for "another sensitive device." I am still not sure what "sensitive" means relative to hardware. Susceptible seems like a far better choice of words. READ MORE

I just returned from chairing the Report on Proposals (ROP) meeting for the NFPA 70B Recommended Practice for Electrical Equipment Maintenance Committee, where we reviewed, debated, commented and voted on more than 150 proposed revisions to the 2002 edition for the next edition. By the time this article is published, the ROP will be published for public comments. READ MORE

Simple questions to tackle audits or troubleshooting jobs Last month's article focused on having the right tool for the job. When conducting a power-quality audit or carrying out a troubleshooting job, the right tool is just one part of the process. You next have to figure out how to go about using those tools to achieve the objective. READ MORE

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
