РАСЧЕТ ЛИНЕЙНОЙ ЭЛЕКТРИЧЕСКОЙ ЦЕПИ
ТРЕХФАЗНОГО НАПРЯЖЕНИЯ
Задание:
Для электрической цепи, приведенной на рисунках №№ 3.1 – 3.17 по заданным в таблице параметрам и линейному напряжению Uл определить:
-
Фазные и линейные токи, а также ток в нейтральном проводе (для четырехпроводной системы);
-
Разность потенциалов между нулевыми точками (для трехпроводной системы);
-
Активную, реактивную и полную мощность каждой фазы;
-
Построить векторную диаграмму токов и напряжений на комплексной плоскости.
