Abstract

1415316 Transformers NORTH ELECTRIC CO 21 Nov 1972 [16 Dec 1971] 53762/72 Heading HIT [Also in Divisions G3 and H2] A transformer for use in a ferroresonant regulator circuit (see Division G3) comprises a composite core structure consisting of a first nickeliron core T s and a second sintered core L s made of ferrite or molypermalloy. In use, the first core has an initial permeability of 140-200,000 subsequently reducing almost to zero at saturation. The second core does not saturate and has a constant permeability of about 26. The cores may be toroidal, Fig. 2, with input and output windings 18, 24 wound around both. Alternatively, Fig. 4, saturable core T s may be made from E and I laminations, while the second core L s is rectangular. Windings 18, 24 are wound around centre leg 35. An air gap may be ground between windows 31, 33.
