<p>A device (100, 200, 300) for determining a common-mode signal in a power line communication network is provided. The device (100, 200, 300) comprises a first line (102), a second line (104) and a third line (106) that are connected to a first terminal (110), to a second terminal (112) and to a third terminal (114), respectively. The first, the second and the third terminal (110, 112, 114) are configured to be connected to a phase line (P), a neutral line (N) and a protective earth line (PE) of the power line communication network, respectively. The device (100, 200, 300) further comprises a common-mode choke (120) configured to couple out the common signal from the first, second and third line (102, 104, 106), and the common-mode choke (120) is connected to a termination impedance (122) which is higher than an impedance of the power line communication network.</p> |
