Transformers are often integrated in large office complexes or factories in the building. The current flow generates low-frequency alternating magnetic fields that can reach into the work area of employees. The workplace should be installed on the grounds of preventive occupational health and safety as far away as possible from the transformer station. As a guideline, the specification of the TCO standard is used with a value of 0.2 micro Tesla. In confined work spaces, the question may arise whether a shielding of the alternating magnetic fields is possible.
