摘要

The power supply system has several adjacent current conductors forming single-conductor transformers with iron iron cores carrying secondary windings. To avoid the adjacent conductors affecting the fault behaviour of the transformers involved, a screen (15-17) is located between the iron cores (6-8) and the adjacent conductors (3-8). The screen is made of ferromagnetic and/or electrically conducting material. The screen prevents the design errors or faults of one transformer being affected by an adjacent transformer. This means that these errors or faults behave in a predetermined way and can be compensated for.
