Abstract :
Presents a concept of the measurement of Budeanu reactive power in nonsinusoidal systems, based on the wideband π/2-phase-shift networks. An example of such a meter for a band of ten harmonics is given. The measurement error due to imperfections of the π/2-phase-shift networks is also analyzed.
