| Abstract(in English) | Measurements on the leaked electric field, when the in-house broadband power line communication (PLC) devices are in use, have so far been made with the separation distance not exceeding 10m. We measured the field strength farther than 10m, that has not been known, and found cases that the field strength exceeds the ambient noise by more than 20dB at the separation distance of 30m. We also made "direct" measurements on the common mode current (CMI) "on" the in-house power line, that has been regarded as the source of the leaked field, and found cases that the CMI exceeds the CMI limit for the Japanese PLC devices by more than 20dB. |
