Abstract :
Established circuits for measuring or detecting power, reactive power, or power factor, have an inherent time delay, mainly because of the need to filter the output. This letter describes simple and novel circuits in which no filtering is necessary, and which therefore offer substantial advantages in control and monitoring system applications.
