Abstract： Starting from the comparison between power quality meter and multi‑functional meter,this paper discusses the application scenarios of power quality meter according to the characteristics of airport project and in combination with airport cases. The suggestion of the power quality meter installed at the sensitive equipment without UPS protection and the medium voltage inlet of the substation is given.
