Concerning the meter.

住宅内と住宅外で同一周波数帯を使用する電力線通信が利用される場合には、通信に使用する信号が混在することになり、通信速度が低下したり通信が阻害されたりする。また、低圧配電線は１つの変圧器から複数の需要家へ電力を供給していることから、宅内での通信信号が同一変圧器配下の他の場所へ漏洩することになるが、信号には使用者の個人情報等が含まれており、セキュリティ的に好ましくない。これらの問題を回避するためには、電力線の途中で信号を遮断する必要があり、そのための手段としては、住宅への電力線引込口付近、例えば、住宅の分電盤や電力量計付近（メータボックス等）にブロッキングフィルタを設置することが一般的である（特許文献１、２参照）。
特開２００３−２７３７８３号公報 特開２００１−９４４８３号公報 When power line communication using the same frequency band is used inside and outside the house, signals used for communication will be mixed, resulting in a decrease in communication speed or hindered communication. In addition, since the low-voltage distribution line supplies power to one or more consumers from one transformer, the communication signal in the home leaks to other places under the same transformer. User's personal information is included, which is not preferable for security. In order to avoid these problems, it is necessary to cut off the signal in the middle of the power line. As a means for that purpose, the vicinity of the power line entrance to the house, for example, near the distribution board or watt hour meter of the house (meter It is common to install a blocking filter in a box or the like (see Patent Documents 1 and 2).
