Product description

Task 031341-0302-0002 (judgment of ElektroHelp). Three-phase four-star nasimmetrichnaya.

На рисунке представлена схема несимметричной трехфазной цепи, соединенной «звездой» с нулевым проводом с симметричными фазными ЭДС.
1. Фазные напряжения, линейные токи и ток в нулевом проводе (ток в нулевом проводе можно определить графическими построениями).
2. Активную, реактивную и полную мощности, потребляемые цепью.
3. Построить топографическую диаграмму напряжений и на ней показать векторы токов.
Дано: UA = 220 B; R1 = 17 Ом; R2 = 23 Ом; XL = 18 Ом; XC = 12 Ом.

Additional information
