Digital Meter for Active, Reactive and Full Power of Periodic Signals of Complicated Format

摘要

We propose engineering solution of a digital meter of active, reactive and full power of periodic signals of complicated signal format, as well as the equivalent power factor. Operation of the meter is based on the method of excess metering of physical quantities with automatic correction of systematic errors of results of metering with nonlinear function of transforming of measuring converter. This approach is developed by the author together with electrothermal method of metering of power of periodic signals of complicated format. Potential of application of new generation of thermosensitive piezoresonant converters for realization of multiplication operations of two magnitudes is shown.
