<p><P>PROBLEM TO BE SOLVED: To provide a common mode current detector and a power-line communication device, the common mode current detector being enabled to detect an actually generated common mode current to decide its level. <P>SOLUTION: The common mode current detector includes an antenna unit 2 which receives an electromagnetic wave radiated from a power line L or an AC cable 10 connected to the power line L, a detecting circuit unit 3 which is connected to the antenna unit 2 to detect the common mode current generated at the antenna unit 2, and an abnormality decision unit 4 which decides whether or not a detected amount of the common mode current by the detecting circuit unit 3 is larger than a predetermined value. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
