IEC61850将数字化变电站分为过程层、间隔层和站控层3层，各层内部及各层之间采用高速网络通信。与常规变电站相比，数字化变电站间隔层和站控层的设备及网络连接只是接口和通信模型发生了变化，而过程层却要进行较大的改变。由传统的电流、电压互感器、一次设备以及一次设备与二次设备之间的电缆连接，逐步改变为电子式互感器、智能化一次设备、合并单元(MU)、光纤连接等内容，过程层各设备之间的数据交换遵循IEC61850-9-1/2或IEC60044-8标准的要求。而电子式互感器是数字化变电站中的关键设备。FANUC ROBOTICS PCB DAUGHTER BOARD A20B-2902-0236/?02A
