After the break off, when the harmonic voltage distortion rate of a detection voltage, where the system voltage of high-voltage mains 1 is detected by a transformer 10 for a measuring instrument, becomes smaller than a prescribed value, a high-voltage electromagnetic contactor 6 is thrown to improve the power factor of the system.例文帳に追加

遮断後は高圧幹線１の系統電圧を計器用変圧器１０で検出した検出電圧の高調波電圧ひずみ率が所定値より少なくなると、高圧電磁接触器６を投入して系統の力率改善を行う。 - 特許庁
