摘　　要：分析了常见的50Ω/50μH+5Ω和50Ω/5μH+1Ω两种不同V型人工电源网络的差异,对直流电能表分别使用这两种电源网络进行端子传导骚扰的测量,在典型频率点的测量结果进行了分析比较。对直流电能表的端子传导骚扰测量来讲,50Ω/50μH+5Ω网络可用作摸底性测试,而标准符合性测量结果必须以50Ω/5μH+1Ω网络为准。The differences between two different V-type artificial mains networks,50Ω/50μH + 5Ω and 50Ω/5μH +1Ω,are analyzed and the measurements of terminal conducted turbulence at typical frequency points are compared for the DC power meter using each of the two artificial mains networks. The 50Ω/50μH + 5Ω network can be used as the baseline test for the terminal conduction disturbance measurement of DC power meter,while the standard compliance measurement result must be based on the 50Ω/5μH + 1Ω network.
