Abstract

1,244,219. Transformers and inductors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 23 Aug., 1968 [24 Aug., 1967], No. 40387/68. Heading H1T. [Also in Division H2] An arrangement for compensating capacitive current in a 3-phase supply comprises a plurality of magnetic circuits each of which is energized by only one phase winding PW and a pair of differential D C. biasing windings GW, each associated with a magnetic circuit of the corresponding phase winding. Each phase winding may be divided into two equal component windings, each of which energizes a magnetic circuit. Six further windings DW may be employed for harmonic suppression. A fixed reactor #<SP>V</SP> may be switched in series with any of the windings and has specified inductances relative to that of the saturated main core. The magnetic circuits may be carried by three two- or three-limbed cores (Figs. 9-11, not shown), the D.C. limbs of which may be split or by six two- or three-limbed cores (Figs. 7, 8, not shown). Figs. 12 and 13 (not shown) relate to eight-limbed cores. The biasing current in windings GW may be automatically controlled in dependence on voltage, current, power factor, active or reactive power. Secondary windings may be included to feed loads. The arrangements are applicable to compensation for capacitive current in cable networks or to the adjustment of capacitor banks.
