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 ...

Jim Williams was always intrigued by RMS measurement. Implicit computing RMS-to-DC converters like the old Analog Devices modules, and later the monolithic devices, were interesting to him from a ...

Some measurements, like “peak to peak amplitude” are pretty straightforward. But when should you use “mean” and when should you use “RMS”? What exactly is RMS, and what’s the difference between “RMS” ...

AEMC's Sentinel Current Data Loggers are a new line of loggers that record true RMS measurements of current parameters. The current loggers include integral flexible current probes for three-phase ...

Milpitas, CA. Linear Technology has introduced the LTC5596, a high-frequency, wideband and high dynamic-range RMS power detector that provides accurate, true power measurement of RF and microwave ...

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 ...
