POWER-LINE CARRIER COMMUNICATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method for superimposing communication signals between multiple power line pairs using a single signal transformer in a power-line carrier communication apparatus. SOLUTION: In a power-line carrier communication apparatus for conducting communication using multiple wire system power lines such as a single-phase three-wire system, a three-phase three-wire system, and a three-phase four-wire system, the purpose of this invention is attained by a power-line carrier communication apparatus, characterized in that the communication signals are superimposed between multiple power line pairs using a single signal transformer.
