| Abstract: | To solve the clock error problem of the smart electricity meter, an active timing smart electricity meter is designed based on the low-frequency time-code timing technology. The low-frequency time-code receiver is added on the meter. The meter receives the timing signal automatically at the initialization or following the set time interval. The time signal is decoded and write into the meter. The time calibration of the meter is solved and the clock accuracy can reach 0.5 second per month. |
