Abstract
890,818. Interference filters. BELLING & LEE Ltd. Nov. 4, 1960 [Nov. 20, 1959], No. 39400/59. Class 40(8). An interference suppressor comprises a filter network having two coils, e.g. L 2 , L 3 , Fig. 2, or L 6 , L 7 , Fig. 4, wound on a single continuous core either in series or parallel in the live lead of a power transmission line, the coils being wound and dimensioned so that fluxes induced in the core at 50 c/s cancel each other out. Thus the 50 c/s current does not saturate the core and the windings present an effective inductance to radio frequency currents which it is desired to suppress. The coils are combined with shunt capacitors as shown to form either a single or double # filter section.
