共模噪声是从交流输入线流入大地的干扰电流，差模噪声是在交流输入线之间流动的干扰电流。对任何电源输入线上的传导EMI噪声，都可以用共模和差模噪声来表示，并且可把这二种EMI噪声看作独立的EMI源来分别。在对电磁干扰噪声采取措施时，主要应考虑共模噪声，因为共模噪声在全频域特别在高频域占主要部分，而在低频域差模噪声占比例较大，所以应根据EMI噪声的这个特点来选择适当的EMI滤波器。电源用噪声滤波器按形状可分为一体化式和分立式。
GB/T12325-2008《V锥流量计》中规定：电能质量分析仪的35kV及以上供电电压正、负偏差值之和不超过标称电压的10%；20kV及以下三相供电电压允许偏差为标称电压的土7%；220V单相供电电压允许偏差为标称电压的+7%，－10%。三相电压不平衡GB/T15543-2008《电能质量三相电压不平衡》中规定：电力系统公共连接点电压不平衡度限值为：电网正常运行时，负序电压不平衡度不超过2%，短时不得超过4%；低压系统零序电压限值暂不做规定，但各相电压必须满足GB/T12325的要求。

为了校准5500550255205522A等型号多产品校准器的交直流电压、交直流电流和电阻五项主要功能，使用的标准设备必须满足校准不确定度比率的要求，即被校仪器的不确定度与校准标准的不确定度之比率TUR至少大于4:1或者3:1。本文对这五项校准的测量不确定度的要求进行了讨论分析了使用不同标准设备时的校准不确定度和不确定度比率。分析表明，要完成这五项功能的校准，需要8508A高精度数字多用表，A40B精密分流器，5790A交流电压测量标准或者其他类似的标准仪器；在直流电压和电阻的几个校准调整点还需要应用校准边界保证（Guardbanding）技术或者使用其他的测量仪器。

PLC
处理器(CPU)由控制器、运算器和寄存器组成并集成在一个芯片内。CPU通过数据总线总线、地址总线、控制总线和电源总线与存储器、输入输出接口、编程器和电源相连接。
小型PLC的CPU采用8位或16位微处理器或单片机，如8031、M68000等，这类芯片价格很低；中型PLC的CPU采用16位或32位微处理器或单片机，如8086、96系列单片机等，这类芯片主要特点是集成度高、运算速度快且可靠性高；而大型PLC则需采用高速位片式微处理器。
CPU按照PLC内系统程序赋予的功能指挥PLC控制系统完成各项工作任务
