Tóm tắt

Nowadays, with the development of the industries, the electrical types of equipment are used and applied widely for many different purposes. One of them is the use of power cables to transmit electricity over long distances, from generator stations to consumers. Local and global fields are usually created by the extensive presence of the types of currents following in power cables in general and underground cables in particular. Not only causes directly some unwanted effects on the body’s natural equilibrium, but electromagnetic fields can create the disturbance and cause interference with electronic devices. In this paper, a shielding plate is introduced to mitigate the local fields generated by a three phase current of underground power cables. The computation of magnetic fields is implemented with the magnetic vector potential formulations via a finite element technique. The developed method is applied to a practical problem.
