  • 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

While renovating a basement, I came across a poster for “The Endless Summer,” a film released 50 years ago in which two surfers travel the world’s oceans, chasing warm weather and surfing adventures. It reminded me of a meeting with a group of executives in a multibillion-dollar company 25 years ago. READ MORE

The quote “The more I learn, the more I realize how much I don’t know,” is popularly attributed to Albert Einstein. The sentiment accurately summarizes analyzing the power quality (PQ) and quantity data collected over the past year at a residential site with 14 kilowatts of photovoltaic (PV) roof panels.

The PQ industry has lost another giant with the passing in June of Erich Gunther, formerly of Electrotek Concepts and co-founder of Enernex. Erich had a unique capability to be truly a jack-of-all-trades and master-of-all, with regards to the utility electrical and communication systems, electronic instrumentation design, and programming of complex algorithms in software and firmware.

My January 2015 article, “It’s Just Math,” explained how various parameters used to evaluate power quality (PQ) are derived while avoiding formulas and other mathematical expressions. This article follows up on testing operational aspects of PQ monitors to verify that they meet your application’s needs. READ MORE

A while back, I wrote about a house with 14 kilowatts (kW) of solar panels installed on the southern exposure roof. Voltage and current monitoring at the breaker panel prior to the solar panel installation had shown 10–12-volt (V) deep sags occurring as frequently as every 22 minutes. READ MORE
