Voltage sag is a temporary drop in RMS voltage levels in electrical systems, usually caused by faults, motor startups, or ...

If you measure a DC voltage, and want to get some idea of how “big” it is over time, it’s pretty easy: just take a number of measurements and take the average. If you’re interested in the average ...

On infrequent occasions, I am asked to design a circuit to measure the RMS value of a current or voltage for some kind of power measurement. Since the work I do is hardly unique, I thought some of you ...

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 ...

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 ...

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.

So I'm finalising a set-up for my new build & I'd really like to get it right this time. I have an amplifier rated at RMS 330 watts (Max 600) x 1 channel at 4Ohms (from Sony) > The Amplifier will ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...
