| Abstract: | The precision of the clock inside the electric energy meter is a crucial factor for the overall accuracy of the electric energy meter,so it is necessary to analyze the clock error of electric energy meter.A clock error analyzer for the electric energy meter based on PIC SCM is presented.Measuring precision is greatly increased by the multi-cyclical synchronization frequency measurement.The configuration of hardware and designing idea of software of this system are introduced in detail.This system could achieve quick and precise measurement of the clock error for Watt-hour electric energy meter. |
