Abstract: This paper reviews evolving methods of reactive power measurement in a harmonic environment. First, the definitions of reactive power under harmonic condition are presented. The regulatory aspects of reactive power billing of various countries are analysed indicating the necessity of an accurate method for reactive power monitoring. Several measurement techniques adopted by reactive power meters are discussed and their accuracy in harmonic environment is evaluated based on experimental investigations reported in research articles. The paper highlights the necessity of a standardised method for measurement of reactive power accounting for disturbance from harmonic sources.

Keywords: reactive power; non-active power; harmonic distortion; measurement techniques; power quality; measurement errors.
