Simple power quality problems often evolve into tangled webs that take a long time to unravel. As commercial and industrial systems become more integrated and rely more heavily on bidirectional information from multiple sources that are powered from different supplies, it can take considerable time to understand the interdependencies of how one part acts and reacts to the others.

When using a power quality monitoring instrument, there are some “gotchas” to watch out for; otherwise, your efforts can either be wasted or, perhaps worse, misleading by coming to conclusions that aren’t valid. The complete list is much longer than the one below, but these are among the top of the hit parade.
 Measuring with equipment not suitable for what one wants to observe

The meteorological events in the northeastern United States in October 2012 provided some interesting discussions on electric power. Unfortunately, anyone with a reasonable knowledge about the electrical distribution system or electricity in general would challenge the credibility of some of the sources. READ MORE

When it comes to new construction of the electrical infrastructure within a facility, the National Electrical Code (NEC) is the most common source of rules and regulations with regard to what to do and how to do it. Many people take the attitude that “if built to Code,” everything should work just fine, including with respect to the power quality aspects.

More new lighting designs and retrofit projects are turning to alternative technologies for facility illumination. Besides the efficiency mandate that has boosted sales of new incandescent lamps, saving money on the electric bill due to improved efficiency seems to make the newer luminaire types a win-win.

When I was learning carpentry from a master carpenter, I tried to do something with a tool close at hand instead of going to get the correct tool for the job. Of course, I butchered the piece of wood and eventually had to get the right tool, which got the job done in a fraction of the time that I wasted with the convenient-to-reach tool. READ MORE

A significant portion of the standard-making process goes beyond just rules and requirements. It is especially true for the standards developed by the Institute of Electrical and Electronic Engineers’ (IEEE) Power Quality Subcommittee, which produced a roadmap in 2006 to identify gaps or outdated information. The following are some of those documents that are worth reading. READ MORE

With the Institute of Electric Efficiency reporting more than 36 million smart meters installed from 2007 through May 2012 and a target of 65 million by 2015, it appears that smart meters are here to stay. READ MORE

On most distribution networks (except maybe in rural areas), the voltage levels typically reduce to a couple of percentage points from nominal when the sun rises, people wake up and they start using more electricity. Conversely, as the sun sets, the voltage creeps back up, and by 10 p.m. or so, it usually gets a couple of percentage points above nominal. Figure 1 below shows such a pattern. READ MORE
