Inductive coupler of high current and current transformer for power lines

摘要

"Inductive coupler of high current and current transformer for power lines." It is provided with a data coupler coupled to power lines (10).The coupler (10) includes (a) a magnetic core (105) having a high magnetic permeability in a frequ00b3u00eancia data communication and being configured to allow a line of potu00eanciThe (100) serves as a primary winding, (b) a circuit for signalling data, which provides a secondary winding (115), through the magnetic core (105).For coupling a data signal between the power line (100) and a communications device (130), and (c) a coil self induction reactance (135).Coupled to the circuit data signalling.To create a stream of frequ00b3u00eancia power flow opposite in direction and cancellation of comparable in magnitude to a stream of frequ00b3u00eancia power.The coupler (10) can also include a circuit for sensing a level of current in the power line (100).
