<p>PROBLEM TO BE SOLVED: To provide a common mode conduction disturbing wave measurement device capable of accurately measuring a common mode conduction disturbing wave at a high frequency and in a wide band.SOLUTION: In a common mode conduction disturbing wave measurement device 1 for supplying single phase commercial AC from a power supply part 50 via a power supply impedance stabilization means 10 to a test device, an electromagnetic shield 40 is disposed between the power supply impedance stabilization means 10 and the power supply part 50, and currents passing through first power supply lines 31a and 31b are allowed to flow to a first internal conductor 42a, and currents passing through second power supply lines 32a and 32b are allowed to flow to a second internal conductor 42b, and electromagnetic fields generated in the first and second internal conductors 42a and 42b are mutually offset by differential mode currents, and electromagnetic fields generated in the first and second internal conductors 42a and 42b are allowed to act on a monopole antenna 60 by common mode currents so that it is possible to measure a common mode conduction disturbing wave within the corresponding frequency range of an antenna.</p> |
