Defining and measuring reactive power in non-sinusoidal alternating circuit containing harmonic are always dif- ficult problems in electric measurement.A new kind of hardware circuit and software realization of reactive power meter has been designed in this paper,based on the new definition of reactive power in non-sinusoidal alternating circuit.The e- lectric power meter can display reactive power which was produced by fundamental wave and every harmonic separately. Finally,the future work on the improvement of reactive power meter was proposed.
