The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

In order to measure the RMS value of an alternating voltage an accurate converter is required to produce the true RMS value of its alternating input as a DC output. With simple sinewave inputs the RMS ...

A few months ago a personal computer trade magazine reviewed surge voltage protective power strips for home use. The article offered an explanation of what “120 volts RMS” power (what we typically ...

A “loose neutral” in a residential location can cause equipment damage and even a house fire. An open neutral may start as a high-resistance connection that shows subtle signs in waveform capture data ...
