Abstract
A circuit and system having an inductive data link from one or more user-side phases to a plurality of line-side phases by individual data transformers having a winding coupled to the particular phase by a high-permeability ferrite material. The resulting connection across the primary (or primaries) and secondary (or secondaries) selectively provides and efficient coupling of data in a multi-phase environment including step-down distribution transformers and 'Δ'-to-'Y' configured circuits while maintaining isolation at the power line frequency. Further embodiments include transfer to selected phases or single-phase applications, and selective signal-pass or -reject filtering.
