DEVICE FOR THE TWO-WAY INDUCTIVE COUPLING OF DATA SIGNALS TO A POWER LINE

摘要

Device for the two-way inductive coupling of data signals to a power line The device comprises a current transformer having a ring-shaped magnetic core (10) internally defining an opening (15) for the arrangement of a power line (2) and a winding wound onto the core (10), the core (10) being split into at least two core segments (A, B) articulated to one another. Both core segments (A, B) are furthermore optimized with regard to surface finish and form factor to allow low attenuation in the low-frequency data signal between 50 kHz and 600 kHz transmitted to the power grid.
