Shielding of Magnetic Fields of an Electrical Substation

Sybrand Zeinstra1
1Demcon Multiphysics, Enschede, the Netherlands

Normally, power lines for electrical power distribution are shielded such that there is (almost) no magnetic field outside the cable. In a substation, these cables are connected to transformers via unshielded components such as switching boards and busbars. Thus, magnetic fields are ... En savoir plus
