Description
以下に、第1実施形態に係るテーブルタップとそれを用いた電力測定方法について、添付図面を参照しながら説明する。
ップの高コスト化を防止できる。
2の回路基板25に送信したりする機能を有する。
その算出は、図11を参照して説明したように、演算部33が差δVに対応する瞬時値I(t)を読み取ることで行われる。
本実施形態では、第1実施形態で説明したテーブルタップを利用した電力測定システムについて説明する。
第1実施形態では、式(2)により皮相電力値Sを算出するに際し、電源電圧の実効値Vrmsとして既知の値(100V)を使用した。
本実施形態では、演算部33が電源電圧の瞬時値V(t)を以下のように算出し、それをプラグ差込部1a毎の電力の計算に使用する。
図20は、本実施形態に係るテーブルタップ101の外観図である。なお、図20において、第1実施形態で説明したのと同一の機能を有する要素には第1実施形態におけるのと同じ符号を付し、以下ではその説明を省略する。
図27は、テーブルタップ101の分解斜視図である。
