Some problems about standards of grounding and EMC in electronic,communication,information and computer systems
Bingwen Liu · Electric Power · 2004
According to the practical investigation, the successful experiences and existing problems about the lightning protection systems of large-scale computer, communication and electronic equipment are reviewed. The problems about lightning protection, grounding and EMC standards are analyzed, and the improving suggestions on these subjects are presented. The standards, the SPD (MOV)/mA maximum continuous operating voltage standard, the SPD/ class 1 surge arresters current test wave form 10/350 靤 and its maximum shock current Iimp, are called in question in the paper. Some national and foreign standards, which have been successful and practical used for a longtime, are described and analyzed, and some appropriate standards for concerned subjects are also suggested in this paper.
