In the September issue, I discussed some of the claims that various organizations working on the smart grid have made in the two years since the Energy Independence and Security Act of 2007 passed. The act contained Title XIII, which has 10 characterizations of a smart grid.
Recently, I needed to dig up a paper I wrote more than a decade ago for a conference in the United Kingdom. Part of the paper was devoted to expert systems that were beginning to gain momentum as a possible way to solve power quality problems, rather than just provide more data or information.
My past two columns covered monitoring from the service entrance and down into the facility to record what happened and to determine what caused it. At last, we get down to probably the most important aspect: monitoring at a load to determine why it is not operating properly.
Much of the renewed focus on energy conservation and going green has been on what to do at home and in the workplace. But how about the places where people go to relax and play—resorts and other vacations spots? Are they becoming more green?
Recently, while serving on a panel session at the Power Quality and Reliability conference, a member of the audience chastised me for “not educating us on what this smart grid stuff is really all about.” It seemed like a reasonable challenge, especially given that I am a member of the Institute of
There was a sign at my college job: “Engage brain before opening mouth,” which is similar to what my parents would often say: “Think before you speak.” The same basic concept applies before you take a power quality monitor into the field, connect it up and collect gigabytes of data.
Most facilities have a hidden source of cash within their walls. People working in the energy-reduction field know that usually at least a 10 percent savings in energy can be achieved with a payback measured in less than two years, and often right in next month’s utility bill.
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.
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 c
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.
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).
Businesses, especially in the financial community, are increasingly reliant on information. This has sent the demand to process and store digital information skyrocketing, turning the heat up on data centers’ computer resources.
Though May is officially National Electrical Safety Month, the statistics for electrocution of electricians indicate that we should make it an everyday event. People have been “playing” with electricity since the 6th century B.C.
