摘要： An economically attractive method to tap low-level electric power from any power line is disclosed. The invention captures power for low consumption electronic components such as communication repeaters and remote sensors. The device snaps onto any power line and functions as a parasitic current transformer. It captures the dynamic magnetic energy that is created by electric current as it flows through the power line and concentrates the resulting magnetic flux into a region where the energy is converted to electricity in a pick-up coil. The difference between the disclosed device and a conventional transformer is that the magnetic flux that is set up in the low-reluctance material of the former originates from alternating current on a power line phase and not from a primary transformer winding as in the latter.
