Magnetic field mitigation of power cable by high magnetic coupling passive loop

In this paper a new concept of passive loop technique called “High Magnetic Coupling Passive Loop” is presented. The proposed shield is characterised by high performances and takes all the advantages of passive and active shields. The shielding technique can be adopted in different application field: power lines, busbar systems, line transformer connections, etc.. In the present paper the proposed shielding technique is applied to the junction zone of a high voltage buried power line.
