With the rapid development of national economy in our country ,puts forward higher requirements on power monitor .The traditional power monitor has the weakness of precision ,software and hardware with complex problems . This article introduces a new method of muti‐functional power monitor based on ATT7022E and STM32 chip .This de‐sign gives the overall design scheme of electric power monitor and which describes the overall process of hardware compo‐nent and software design in detail .The test shows that the power monitor three‐phase voltage RMS relative error less than 0 .5% ,meets the power monitor voltage measurement accuracy within 0 .5 specifications requirements .
