摘　　要：介绍了设定在三相电子式电能表中的自检功能软件。指出在电力系统发生故障或出现其他异常现象影响到三相电能表正确计量时,表计可准确记录下运行事件及时间,为日后分析和解决问题提供了充分依据,并及时进行修正电量,保证了电能准确计量。This paper introduced the self-checking function software in three-phase electric energy meter. It is pointed out that the three-phase electric energy meter can accurately record the running events and time, when the power system malfunctions or other abnormal phenomenons occur which affect the correct measurement of three-phase electrical energy meter. It provides the sufficient basis for analysis and problem solving, and timely amends the electric quantity to guarantee the accuracy of electric energy metering.
