sink or source of reactive power odbiornik lub źródło mocy biernej Explanation: Induction machines are some of the most common types of loads in the electric power system today. These machines use inductors, or large coils of wire to store energy in the form of a magnetic field. When a voltage is initially placed across the coil, the inductor strongly resists this change in a current and magnetic field, which causes a time delay for the current to reach its maximum value. This causes the current to lag behind the voltage in phase. Inductors are said to "sink" reactive power, and thus to cause a lagging power factor. Induction generators can source or sink reactive power, and provide a measure of control to system operators over reactive power flow and thus voltage.[6] Because these devices have opposite effects on the phase angle between voltage and current, they can be used to "cancel out" each other's effects. This usually takes the form of capacitor banks being used to counteract the lagging power factor caused by induction motors. https://en.wikipedia.org/wiki/AC_power cccc PL jakość energii elektrycznej kompensacja mocy biernej odbiornik mocy biernej źródło mocy biernej współczynnik mocy EN electric energy quality reactive power compensation reactive power receptor reactive power source power factor http://yadda.icm.edu.pl/baztech/element/bwmeta1.element.bazt... |

"pobierać" lub "wytwarzać" moc bierną Explanation: Tutaj chyba miało być jako czasownik: to source (=produce, generate) or sink (=absorb) reactive power --- "pobierać" lub "wytwarzać" moc bierną Jeszcze można by sprawdzić czy jest to moc bierna indukcyjna czy pojemnościowa, zależnie od elementu czy urządzenia w sieci, ale tego pytanie nie obejmuje. -------------------------------------------------- Note added at 2 days 12 hrs (2020-07-13 12:55:26 GMT) Post-grading -------------------------------------------------- to 'sink' or 'source' reactive power |
