power factor

名詞

(electrical, engineering) The ratio of the actual power to the apparent power in an alternating current power system; specifically, the cosine of the phase angle between the voltage and the current.

日本語の意味

電力因数：交流電力システムにおける実際の力（有効電力）と表面的な力（皮相電力）の比率。これは、電圧と電流の位相角の余弦値に相当する。

The power factor in the factory's electrical system fell to 0.75, increasing reactive power losses and prompting engineers to install corrective capacitors.

工場の電気系統での力率が0.75に低下し、無効電力損失が増加したため、技術者たちは補償用のコンデンサを設置した。

意味（1）

(electrical, engineering) The ratio of the actual power to the apparent power in an alternating current power system; specifically, the cosine of the phase angle between the voltage and the current.

The power factor is of interest because it is a measure of the power which does useful work.
