Abstract :
A system for performing active and reactive power measurements from 50 Hz to 20 kHz is described. The technique is an extension of a power bridge based on a current comparator capacitance bridge that was originally restricted to power frequencies. A digitally-synthesized dual-channel signal source provides the required voltage and current signals.
