This paper introduce a verification platform for power quality monitoring equipment, the platform can test power quality monitoring equipment in measurement method ,measurement accuracy and steady-state verification three aspects, which proposed by IEC 61000-4-30.It can also provide a reference for specification of power quality monitoring equipment. Besides, according to the contents of verification, a waveform database can be built and used for test. The following experiment proved that the platform can fulfill all verification test of power quality monitoring equipment, which has some practical value.
