摘　　要：在电力系统继电保护设备中，因为出现系统故障时产生各种电磁干扰信号既大又复杂，要保证保护设备的正确动作，电磁兼容性设计，特别是控制快速瞬变脉冲群干扰信号对保护设备影响的设计显得非常重要。本文重点讨论控制瞬态干扰的方法、多层电路板布线规则、去耦与旁路、接地技术等。The jamming signals of electric power during system fault is very trickiness, the relay protection must guaranteeing the safety of the system, so electromagnetic compatibility, in particular anti-EFT burst jamming is of the utmost importance for guaranteeing the safety of the relay protection system, in this paper, the main analysis the method of anti-EFT burst jamming, the wire layout of Multi-Layer Printed Circuit Board, decoupling and bypass, grounding.
