9 power coefficient
коэффициент мощности
Скалярная величина, равная отношению активной мощности двухполюсника к полной мощности.
[ ГОСТ Р 52002-2003]
коэффициент мощности (цепи)
Отношение активного сопротивления к полному сопротивлению при промышленной частоте в эквивалентной цепи, которая считается состоящей из последовательно соединенных индуктивного и активного сопротивлений
[ ГОСТ Р 52565-2006]EN
power factor
under periodic conditions, ratio of the absolute value of the active power P to the apparent power S:
NOTE – Under sinusoidal conditions, the power factor is the absolute value of the active factor.
[IEV ref 131-11-46]FR
facteur de puissance, m
en régime périodique, rapport de la valeur absolue de la puissance active P à la puissance apparente S:
NOTE – En régime sinusoïdal, le facteur de puissance est la valeur absolue du facteur de puissance active.
[IEV ref 131-11-46]
Для синусоидального тока коэффициент мощности равен косинусу угла сдвига фаз между напряжением и током, т. е. равен Cos φ.
После того, как стали массово применяться такие нелинейные нагрузки, как компьютеры и другое офисное и телекоммуникационное оборудование, термин коэффициент мощности перестал быть синонимом термина Cos φ.Тематики
