Abstract： This paper studies the principle of electromagnetic induction， uses the current transformer to extract energy directly from the cable， so as to solve the power supply problem of the power line monitoring equipment; uses the current transformer to obtain electric energy through electromagnetic induction， and supplies electric energy to the power line on-line monitoring equipment through rectifier and filtering. Through the simulation experiment in the laboratory， the equipment can extract energy stably under different current states， and the practicability of the energy extraction equipment is verified.

Keywords： electromagnetic induction; energy extraction coil; rectifier filtering
