On the other hand, many advanced reactive energy measure techniques are developed with the progress of micro-electronic technologies. In this paper, after the sinusoidal reactive power theory and the sinusoidal reactive energy measuring techniques are expatiated, an emphasis was given upon the investigation of non-sinusoidal reactive power theories and nonsinusoidal reactive energy measuring techniques. Finally, the developments of reactive power theories and reactive energy measuring techniques are discussed.   Key words：Reactive power；Reactive energy；Measurement；Theory；Phase-shift method；Transformation method
