Abstract :
The development, design, construction, and partial evaluation of a system for performing active and reactive power measurement from 50 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. The design features and component characteristics for wideband operation are emphasized. A digitally synthesized, dual-channel signal source provides the required voltage and current signals
