Abstract:The electromagnetic interference which has an influence on the secondary cable in substations is analyzed,with comparison of the different anti-electromagnetic interference effects when secondary cable shielding grounding schemes are in different electromagnetic interference coupling,especially in the inductance coupling.The measures used to improve anti-electromagnetic interference ability are proposed,which have a very important role in the safe and steady operation of the microprocessor protection device.

keywords: secondary cable electromagnetic interference anti-interference grounding
