Apparatus for screening appliances from high frequency interference

摘要

An apparatus for screening appliances from high frequency interference from the mains supply electrically connected to the appliance has an interference filter being incorporated in the mains plug and comprising at least an induction coil and a capacitor. The capacitors normally used to screen from asymmetric oscillations between the neutral conductor and phase conductor on the one hand and the protective conductor on the other are replaced by a screen of sheeting for the conductor leading from the plug to the appliance. The screen of sheeting is joined to the protective conductor.
