Single-phase transducers in the MVTR and MCTR series fromOhio Semitronics measure voltage and current in applications requiring a trueRMS calculation of the transducer input. Intended for use in ...

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 ...

There are many reasons why one would want to measure voltage and current in a project, some applications requiring one to measure mains and even three-phase voltage to analyze the characteristics of a ...

The continuing emphasis on smart power has increased the importance of power meters, monitors, and analyzers. They all measure rms voltage, current, and power but differ in how and where they are used ...

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 ...
