Abstract: A power metering automatic product with communication function comprises a data collector (101), a data processor (102), a memory (103 and a communication module (104.The data collector (101) is used to collect signals of current and voltage. The data processor (102 is used to transform the signals of current and voltage collected by the data collector (101) into power data of quantity of electricity and load. The memory (103 is used to memorize the power data of quantity of electricity and load transformed by the data processor (102). The communication module (104 is used to transmit the power data of quantity of electricity and load memorized in the memory (103 to a power system server (2) according to the control requirements of the data processor (102).The product is used to acquire the power data collected by a power metering automatic product in time.
