过大PE线电流对信息设备的干扰及其防范措施

IT Equipments Interfered by Excessive Current on PE Conductor and Relevant Precluding Measures

阐述了PE线电流过大的起因、危害及其防范措施。重点分析了过大PE线电流对信息技术设备引起干扰的原因。提出应注意在一电气装置中中性线只能在一点接地以避免产生过大的PE线电流。

The paper presents reasons,endangerment of excessive current on PE conductor and related precluding measures.It emphasizes on reasons of IT equipments interfered by excessive current on PE conductor.The paper points out that N conductor of one equipment must only be grounded at single point to prevent from engendering excessive current.
