Out of sight doesn’t mean out of mind: Probably few industrial/commercial segments are as power-quality conscious as the financial, banking, credit and insurance companies. These “consumers-of-electrons” in the United States generate nearly 10 times the revenue that the “producers-of-electrons” do according to the 2002 U.S. Economic Census ( READ MORE

A power play with hotel elevators In hospitality and gaming facilities, elevators are a vital system—a system that relies on power quality. Generally, the height of these facilities makes the use of stairs an alternative for only a few patrons. One of the keys to operation of elevators is the electric motor and the quality of supply that feeds them. READ MORE

Looking into the origin of disturbances In last month’s issue, we reviewed three types of power quality disturbances that could result in blinking lights. Though the events were categorized as three different types of severity (sag, rapid-voltage change and flicker), they were all capable of causing a visual change in the output of a light source.

Many of the 5th generation power quality monitors can continuously calculate several thousand parameters (more than most users know what to do with or really need). Another parameter has been added—rapid-voltage change—that also can describe what happens when the lights blink. It actually isn’t a new one, but rather one that has just been defined. READ MORE

Odd, even, negative sequence and triplen are all interesting adjectives associated with harmonics. Usually, even harmonics are a rarity. However, in the past couple of years, even harmonics have increasingly appeared in data sent to me by customers. This doesn’t necessarily mean that there is an increase in even harmonics in today’s electrical environment; it’s just that I see it more often. READ MORE

Recently, a PQ consulting expert sent me some interesting data from a facility he monitored. The data was the result of periodic PQ monitoring that is conducted at the facility’s service entrance. There wasn’t a report of problems in the facility, though the resulting data shows several potential problems that may cross that “threshold of pain” in the future. READ MORE
