接于公共连接点的每个用户引起该点负序电压不平衡度允许值一般为1.3%,短时不过2.6%。公用电网谐波GB/T14549--93《电能质量-公用电网谐波》中规定:6~220kV各级公用电网电压(相电压)谐波畸变率是0.38kV为5.0%,6~10kV为4.0%,35~66kV为3.0%,110kV为2.0%;用户注入电网的谐波电流允许值应保证各级电网谐波电压在限值范围内,所以国标规定电能质量分析仪的各级电网谐波源产生的电压谐波畸变率是:0.38kV为2.6%,6~10kV为2.2%,35~66kV为1.9%,110kV为1.5%。

在很多应用场合需要4通道以上的示波器,但是市面上极大部分示波器*多只有四通道,而且没有外部输入的同步时钟接口。有什么快捷的方法获得更多通道功能的示波器?*简便的方法是:将两台示波器的辅助输入信号作为触发源,同时连接到相同的输入信号,每台示波器的另外四个通道都分别连接到不同的待测信号,这样两台示波器就近似于等效的“8通道”示波器。连接示意图如所示。两台示波器连接为近似8通道示波器有些示波器没有辅助输入通道,或者使用辅助输入通道不方便(辅助输入通道在示波器屏幕上没有显示),那么可以使用示波器的某个通道作为触发源,譬如两台示波器都用通道4作为触发源,那么两台示波器就可以同步成近似7通道示波器,连接示意如所示。
