Abstract
A cable coupling trandformer having a metal or ferrite member defining separate high permeability portions of a pair of flux paths, a winding electromagnetically associated with each high permeability portion, and a common low permeability portion of each flux path which passes between a pair of conductors carrying equal currents in antiphase. A portion of the current induced in either the conductors or the windings are impressed on the other to create a simple communications device.
Claims15
A coupling transformer for a pair of spaced electrical conductors bearing substantially equal and opposite currents, comprising a relatively high permeability member disposed in electromagnetic relationship with the conductors;
- the member, in use, defining a pair of flux paths and sharing a further portion, extending between the conductors, of relatively lower permeability;
- and a pair of electrically connected secondary elements each also disposed in electromagnetic relationship with a portion of each of the flux paths defined by the high permeability member.
