摘要
设计了一种连接被检智能电能表与标准表的适配器,在进行射频电磁场辐射抗扰度试验时,利用CALPORT300标准表,测量智能电能表电脉冲输出。实验结果表明,接入该适配器的智能电能表的电脉冲输出波形高电平滑落现象得到很大改善,说明该适配器的输入阻抗大、输出阻抗低,解决了智能电能表误差检定不稳定的问题。
This paper provides a realization of an interface adapter which is coupled in between the impulse measurement circuits of the meter under test and the reference standard. In the radiated immunity test,using CALPORT300 standard meter for smart electricity meters. In addition,it is shown that the adapter is able to alleviate the dropping of the impulse voltage level,which indicates that the adapter has high input impedance and low output impedance,and is very effective for making the error measurement stable and reliable.
