At a recent Technology Committee meeting for a local school district, there was considerable discussion about the lack of responsiveness in getting electrical infrastructure issues fixed. Everyone from the administrators to the principals to the teachers joked about how long such things take to get remedied. READ MORE

At the recent Power Quality World Conference, I chaired a session on “Specifying and Purchasing PQ Equipment.” Afterward, I met one of the presenters from an electric utility who said he planned to bring his lawyer with him to the session the next day. I thought he was joking, until he arrived the next morning, lawyer in tow. READ MORE

A couple of months ago we dealt with lightning and the fast transients that can be coupled onto the electrical distribution system of the utility or within a facility, and the use of TVSS (transient voltage surge suppressors) to minimize the potential damage from such. What I didn’t cover is the need to protect not just the electrical circuit path, but also the communication circuit paths. READ MORE

One of the most power-quality aware industries is the financial market, as it is one of the most dependent on the uninterruptible operation of computer and communications technology equipment for their business to generate “positive money.” It is not surprising that many of the members of the 7x24 Exchange (7x24exchange.org) are from financial institutions.

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
