   Es sei noch bemerkt, dass man bereits Kondensatoren verwendet hat, welche parallel zur Netzspannung liegen. Dadurch sollte die Phasenverschiebung des Belastungsstromes geändert und der Spannungsabfall der Stromerzeuger vermindert werden. Diese Schaltung hat mehrere Nachteile. Der Kondensator hat unabhängig von dem augenblicklichen Werte des nutzbaren Verbrauchsstromes dauernd grössere dielektrische Verluste und wird daher mehr erwärmt ; der Stromerzeuger muss dauernd den voreilenden Strom an den Kondensator abgeben ; bei einem Durchschlage des Kondensators wird die ganze Anlage gestört. Bei der neuen Schaltung   fliesst   durch den Kondensator nur immer so viel Strom als die Verbrauchsapparate aufnehmen. Im Kondensator finden daher dielektrische Verluste nur nach Massgabe des Nutzstromes statt und der Stromerzeuger wird nur mit dem Nutzstrom belastet.

   Ein Kurzschluss in dem Reihenkondensator würde zu keinerlei Störungen Veranlassung geben. Der Stromerzeuger würde einfach so arbeiten, als ob der Kondensator nicht vorhanden wäre.

 EMI2.1
 



   It should also be noted that capacitors have already been used which are parallel to the mains voltage. This should change the phase shift of the load current and reduce the voltage drop of the power generator. This circuit has several disadvantages. Regardless of the instantaneous value of the usable consumption current, the capacitor has continuously greater dielectric losses and is therefore heated up more; the power generator must continuously deliver the leading current to the capacitor; if the capacitor breaks down, the entire system is disturbed. With the new circuit, only as much current flows through the capacitor as the consumption devices. In the capacitor, dielectric losses therefore only occur in accordance with the useful current and the power generator is only loaded with the useful current.

   A short circuit in the series capacitor would not give rise to any malfunctions. The power generator would just work as if the capacitor weren't there.
