对于三相智能电表可以采用同样的方法.在传统的四线系统中,零线被选作电表AFE的接地参考.相电流利用电流互感器测量.电源利用所有三相创建两个电源域：一个为AFE供电,一个为通信模块供电,电源必须进行隔离以保证安全.MCU可以置于任一电源域中,因此AFE与MCU之间（隔离1）或MCU与通信模块之间（隔离2）都存在一个隔离栅.与大型、昂贵、爱普生EPSON晶振难以通过认可的隔离电源相比,这种方法的优势显而易见.数字隔离技术造就了业界很小的UL认可DC-DC转换器,这些IC具有很高的热稳定性和机械稳定性、出色的耐化学腐蚀性以及良好的ESD性能.设计工程师现在可以集中精力改善系统设计,而无需担心隔离问题.三相单相防窃电智能电表IC内置芯片级变压器的单相防窃电智能电表.IC内置芯片级变压器的单相防窃电智能电表

可以将同样的方法IC同时包含隔离电源和隔离数据通道应用于通信模块,因为它也需要一个隔离电源并通过隔离栅进行数据通信.三相智能电表新结构利用AFE1测量从线路电流获得的电气量,利用AFE2测量从零线电流获得的电气量.两个电流均利用不受外部磁场影响的分流电阻测量,日本进口晶振从而消除窃电之忧.AFE2利用一个IC接收功率,该IC包含一个基于数字隔离器的隔离电源.它利用嵌入同一IC并采用相同技术的隔离数据通道与MCU通信.
