TIME DIVISION MULTIPLIER TRANSDUCER WITH DIGITALLY DERIVED PHASE SHIFT ADJUSTMENT FOR REACTIVE POWER AND ENERGY MEASUREMENT

摘要

TIME DIVISION MULTIPLIER TRANSDUCER WITH DIGITALLY DERIVED PHASE SHIFT ADJUSTMENT FOR REACTIVE POWER AND ENERGY MEASUREMENT A power transducer of a variety utilizing time division multiplication and wherein the output of a time division converter is directed to an N position digital circuit such as a shift register or random access memory driven by an incrementing or clock input of predetermined frequency. The pulse train input is replicated at the digital circuit and directed to a parameter responsive switching circuit for carrying out actuation thereof following which filtering is provided to derive a product characterized output.
