摘要

An electrical power supply unit powers a load, in particular a transformer (8), from a power source (10) via electrical switchgear (14), in particular a circuit-breaker, and it includes an interference attenuator (16) of the ferrite type for attenuating interference due to switching. The attenuator (16) is placed between the power source (10) and the electrical switchgear (14), thereby contributing to reducing the extent of the interference significantly.
