  • Capacitors that blew up from a power supply failure
August 2017
In my 40-plus years in the industry, I have analyzed customers’ power quality monitor data files and heard their stories about hundreds of things that have happened in their facilities or homes: some mysterious, some catastrophic, some even comical. The following are just a few common types of PQ-related issues that don’t just happen to “the other guy.”

Over the past two years, the technical committee responsible for IEEE 1547, Standard for Interconnecting Distributed Resources with Electric Power Systems, has added a section on power quality (PQ), including the parameters, indexes and limits on those for distributed energy resources (DERs) connecting to the electrical power system (EPS), including distribution and transmission systems.

It seems like every decade or so, elementary school educators employ a new way of teaching math. When parents try to help, they are greeted with “That’s not how we do it.” Yet the fundamental laws of mathematics haven’t changed since the time of the ancient Greek and Persian mathematicians.

Reviewing data files from power quality (PQ) monitors to find evidence pointing to the cause of a customer’s problems may sound simple enough for someone who has worked in the industry for more than 35 years. However, it is often a challenge to have the customer provide the information necessary to determine what is what.

  • Figure 1: Voltage and current transients during switching
April 2017
Engineers in a large electric utility’s power quality (PQ) department had installed PQ monitoring to determine the source of a system component’s failures. They needed to see the voltage and current waveforms before, during and after the cap banks were switched in and out. READ MORE
  • Figure 1: Power quality phenomena over the voltage range
March 2017
The lights blinked for an instant, or a running appliance made a sound like the motor was slowing down. No digital clocks were blinking, no computers restarted, no production lines stopped. It wasn’t going on continually like light flicker, nor was it severe enough of a voltage drop to be classified as a sag. So what was it?

When I arrived recently at a residential construction site to build a covered porch, the homeowner was busy cutting a tree away from the power lines to the house with a chain saw. It could have led to disaster, but his chain saw skills and carefully attached ropes dropped the tree away from the wires. READ MORE

The proliferation of alternative forms of lighting—for example, LED lamps—has been accelerated by the significantly limited sale of incandescent light lamps. In case you forgot, incandescents failed to meet the efficiency rules of the Energy Independence and Securities Act of 2007. READ MORE

One challenge with going to one of America’s iconic eating establishments—the diner—is that the menu has so many choices that decisions can change a dozen times before the server takes the order. Electrical contractors face a similar challenge when deciding which power quality tool to purchase or rent. READ MORE
