Though lightning season may be over by now, it is worth reviewing the impact storms can have on the operation of a facility. Some may have experienced significant damage to equipment from the high frequency transient energy of lightning strikes. READ MORE

Have a backup solution for when the lights go out It has been several months since the “Blackout of 2003” captured headlines around the world. After the initial coverage of what happened and how many people were sleeping in unusual places, attention eventually focused on how much business was lost during the 12 to 24 hours during which electricity was being restored.

Consider the following statements summarized from a description of a “recent” blackout: • Needles on meters in utility control centers were swinging wildly. • There was a large power surge that suddenly reversed itself and headed north, cascading through grid, as hundreds of generators and transmission lines tripped offline, one by one.

In the past, when power flowed as a sine wave, the square root of three was used to convert between line-to-line voltages and line-to-neutral voltages. One phase could be measured and the results multiplied by square root of three times the square root of three (also known as “3”), to get the three-phase total power. READ MORE

The frequency stability of the interconnected electric grid in North America is a marvel of engineering. As shown in Figure 1, the deviation is rarely beyond 0.05 Hz from the nominal 60 Hz. In fact, during a given hour time period, this deviation is more like +/-0.02 Hz from the nominal value. READ MORE

Getting some people to pay attention to power quality issues is often like trying to sell them insurance; they wonder, “Why bother? It never happens to me.” It becomes a gamble, or as Dirty Harry would say, “Do you feel lucky?” Power quality issues have been around since Westinghouse and Edison debated whether generation should be AC or DC power.

In the latest edition of “Electrical Power Systems Quality” by Dugan, McGranaghan, Santoso and Beaty, the authors point out that “it is commonly stated at power quality conferences and in journals that 80 percent of all power quality problems reported by customers are related to wiring and grounding within a facility.” They go on to explain that “while this may be an exaggeration, many power quali READ MORE

When most people think of the word “government,” the word “regulation” is usually close behind. The government regulates the speed that you can drive on the highways, how much income tax you pay, how much pollution a factory can emit, even which drugs can be sold (legally). Yet there is no federal regulation concerning power quality in the United States. READ MORE

The federal government has been driving the process to develop an interconnected standard to establish the criteria and requirements of distributed generation (also called distributed resources or dispersed generation) to be connected into the utility-owned electric power grid. READ MORE
