SIGNAL-CURRENT LEAD-IN DEVICE FOR THREE-PHASE SUPPLY MAINS Russian patent published in 2001 - IPC

Abstract RU 2165675 C2

FIELD: electrical and communications engineering. SUBSTANCE: lead-in device has power transformer, medium-voltage supply mains, first, second, and third cosine capacitors, first, second, and third passive/active transmitters, and triggering unit. With cosine transformers inserted in low- voltage line signal currents are transmitted through three-phase transformer. EFFECT: provision for organizing communication channels in power transmission lines dispensing with line traps. 1 dwg
